istqb software testing

The decision to become certified is not always easy. You have to weigh the pros and cons: What's in it for me? Is it worth the effort? In the case of ISTQB, it is definitely worth taking a closer look. ISTQB certification is not hyped – in recent years it has established itself as a reliable standard that the entire industry uses as a benchmark. What exactly is behind ISTQB? And why can this certification open new doors for you? That's exactly what we want to show you.

ISTQB stands for the ‘International Software Testing Qualifications Board’. Sounds pretty formal at first, and it is – but above all it means one thing: standardisation. With ISTQB certification, you can be sure that you are working according to recognised international standards. This is important because it ensures that testers worldwide speak a common language, know the same approaches and test methods and are able to ensure the quality of software - no matter where they work.

The organisation defines the knowledge that a software tester should have at various levels - from beginner to expert. This knowledge is mapped in different certificates. The Foundation Level (CTFL) conveys the fundamental basic knowledge of software testing, from the basics of test methods to the first points of contact with test management. For many, this is the first step into a career that is not only well paid, but also varied and challenging.

Do you want more? Then there is the Advanced Level, which offers you in-depth knowledge in specific areas of software testing. And for those who really want to be among the best, there is the Expert Level. At each of these levels, the aim is to ensure software quality – through structured tests, through test processes that are effectively designed and through techniques that are recognised worldwide.

This also means that once you opt for ISTQB certification, you are choosing to work to the highest standards. And that's what sets you apart – you become an ISTQB Certified Tester, someone who knows how to test properly, with a certificate that is recognised worldwide.

An ISTQB certificate does not automatically make you a better tester – but it shows that you have the will and the ability to become one. It is a statement: I am ready to face the challenges of software testing, to continue my education and to maximise the quality of my work. Companies know exactly that with a certified tester, they get someone who doesn't just ‘sort of’ test, but tests according to a clear, structured plan. This means fewer errors, more efficiency and collaboration with developers and requirements engineers that really works.

A major advantage of ISTQB certification is that it provides you with clear training. You start with the Certified Tester Foundation Level, where you learn the basics: test processes, techniques such as white box testing and black box testing, and how to keep the software lifecycle in mind. The software lifecycle is an integral part of the Foundation Level as it provides a comprehensive overview of all steps of the software testing process. The aim is to make you fit for everyday software testing - from test planning to checking the results.

But it doesn't stop at the basics. Depending on where your interests lie, you can develop further. The Advanced Levelshows you how to manage complex test projects, how to correctly assess risks and how to work with other teams in the project. You will learn how test management works, how to develop a test strategy, which methods and techniques help you to organise the test process efficiently, how to make the most of your resources and when test automation makes sense. Finally, at Expert level, you become an expert yourself - someone who not only carries out tests, but also leads test teams and is able to keep even the most difficult projects on track.

The question is: what do you want to achieve? If you want to get ahead in your career, stand out from the crowd and do the really exciting projects – then there is no way bypassing ISTQB certification. And it's not just about the certificate itself. It's about the knowledge, the understanding of the processes and the practice that will ultimately help you deliver the best results.

ISTQB certification is a clear advantage when you are in job interviews. It shows that you have really familiarised yourself with the subject matter. That you are able to develop test strategies, understand and implement test processes and always pay attention to software quality. Companies are looking for software testers who work according to proven standards – and that's exactly what ISTQB offers.

The path to ISTQB certification may not be the easiest. There is a lot to learn, from test methods and test management to the practical application of test techniques. But it's worth it. Because in the end, you are not just a tester – you are a certified tester who knows how to plan, execute and evaluate tests correctly. You are someone who sees software testing not just as a task, but as an opportunity to really improve the quality of a product.

Now that you have a basic understanding of what ISTQB means and the benefits of certification, let's dive deeper into the different levels of ISTQB certification. From Foundation Level to Expert Level – here you will get a comprehensive overview of all levels, including what they offer and how they can help you in your career.

The Foundation Level, or Certified Tester Foundation Level (CTFL), is the beginning of your journey into the world of software testing. It is intended for all those who are looking to enter the world of professional software testing – regardless of whether you have already gained some experience in testing or just want to learn the fundamentals. Here you will gain the basic knowledge you need as a software tester to gain a foothold in the profession. An important part of the Foundation Level is understanding the software lifecycle, as all steps of the software testing process are considered an integral part of this cycle.

To summarise, at Foundation Level you will learn:
● The basics of software testing and the software life cycle.
● Important test techniques such as equivalence class formation and boundary value analysis.
● The basics of test automation to make routine tasks more efficient.

The Foundation Level is often referred to as the ‘first step’, but don't be misled - it's a crucial step. It's about understanding testing not just as a simple task, but as a systematic process that contributes significantly to software quality. At the end of the Foundation Level, there is an exam that tests your knowledge and, if you pass, awards you the ISTQB Certified Tester Foundation Level certificate. This not only shows your future employers that you have mastered the tools of the trade of software testing, but also that you are prepared to invest in your training.

The Advanced Level is aimed at those who have already gained experience in software testing and want to develop their skills further. The aim is to deepen the knowledge you have acquired at Foundation Level and develop new, specialised skills. There are four specialised roles that you can pursue at Advanced Level:

➡️ Test Analyst:

• Focus on functional tests.
• Deriving test cases from requirements to ensure that software quality is maintained.

➡️ Technical Test Analyst:

• Focus on the technical aspects of testing, such as white box tests and performance tests.
• Particularly suitable if you want to go into technical detail.

➡️ Test Manager:

• Responsible for managing the entire test process.
• Learning to organise projects correctly and implement risk management.

➡️ Test Automation Engineer:

• Design and automation of tests.
• Planning and implementing automation processes and documenting these processes.
• Selection of suitable tools and technologies for the respective projects.
• Conversion of manual test processes into automated test processes, continuous improvement of test automation.

At Advanced Level, you will also learn how to organise the entire test process so that the tests run effectively and efficiently. This includes the topic of risk management, which is essential in order to set the right priorities in the project. You will learn how to identify and assess risks and adjust the test effort accordingly.

With the Advanced Level certificate on hand, you are no longer "just" a tester – you are someone who can strategically plan tests, lead teams and optimise test processes. Companies appreciate this and see you as someone who not only masters the basics, but also has the big picture in mind.

The Expert Level is the highest level of ISTQB certification and is aimed at those who want to reach the top in software testing. It is not just about knowledge – it is about experience, the ability to manage complex projects, and an understanding of the entire software development and testing process. There are three modules for the expert level in test management, and two modules for the expert level in test process improvement.

➡️ Your tasks as an ISTQB test management expert:

• Develop test strategies (Strategic Test Management): Create long-term strategies to ensure software quality while taking effectiveness and efficiency into account.
• Manage quality-related project management (Operational Test Management): Manage relationships with third parties, including contractual, communicative, integrative and quality-related aspects, risk management and the reporting and interpretation of test results.
• Managing the team: You take on the personnel management of (distributed) test teams in organisations, manage across organisations and work closely with other stakeholders and departments such as development and project management to maintain quality across the entire organisation.

➡️ Your tasks as an ISTQB test process improvement expert:

• Assessing Test Processes: Evaluation and advice on test improvement processes, taking into account recognised test improvement models and analytical approaches.

• Implementing Test Process Improvement: Ensuring effective implementation of test process improvements within the organisation, taking responsibility for change management and considering success factors.

The expert level is not just about gaining more in-depth knowledge, but also about thinking strategically. You will be responsible for the entire testing strategy of a company or project, from conception to implementation. Collaboration with other teams plays a central role here – whether it's with developers, requirements engineers or project management. As an expert, your job is to bridge the gap between quality assurance and software development, ensuring that the software meets the requirements.

With the Expert Level certificate, you demonstrate that you are able to take responsibility for the quality assurance of a project or an entire company. It is proof that you have the big picture in mind and can perform quality assurance at the highest level. As a testing expert, you know that software testing is not only a technical task but also a strategic one that influences the entire development.

Now that you know what you can expect from the various ISTQB levels, a crucial question remains: what specific advantages will ISTQB certification actually provide you with in your professional life? Whether it's better job opportunities, a steeper career ladder or simply more job security – with ISTQB certification, you'll get more out of it.

ISTQB certification shows that you are ready for this – and gives you the knowledge you need.

Theory is one thing – practice is another. What do those who have already gone down the path of ISTQB certification say? Here are some testimonials from software testers who have taken their careers a decisive step further with ISTQB certification:

• Thorben F.: Thanks to my ISTQB certification, I was able to start working on customer projects at my new employer straight away. The certificate was the necessary proof for the company.
• Anja K.: The ISTQB certification helped me to structure my practical knowledge in my own head as well. I was able to get to the very centre of my strengths in the job interview.
• Svenja S.: We are all ISTQB-certified in the team and didn't think it was that valuable. Then a new colleague arrived and confused the terms test report and test log, for example. That's when we realised that we were doing a lot of things professionally in our day-to-day work thanks to the ISTQB basics. He is now also registered for the Foundation Level.

The testimonials clearly show that ISTQB certification is not just a formality. It has had a lasting impact on the careers of those who have completed it. It has not only given them access to better jobs, but also the confidence they need to make a real difference in the dynamic world of software testing.

The decision to tackle the ISTQB certification is a big step in your career as a software tester. But how do you prepare effectively without getting lost in the sheer volume of content? The answer lies in a well-thought-out plan that combines theory, practice and a little patience. To ensure that the path to certification does not become a hurdle, but remains an opportunity to develop yourself further, here are some tried and tested approaches summarised for you:

Successful preparation starts with a structured approach. It's not just about reading the entire syllabus once – it's about understanding the knowledge in depth and being able to apply it. For many, this means taking a little time each day rather than cramming everything through at the last minute. Small but regular learning units are often more efficient because they give you the opportunity to process the knowledge bit by bit and memorise it permanently. Exams play a central role here, as they form the basis for an internationally comparable certification in software testing.

The combination of theory and practical applications is the key here. Whilst reading the official materials is important, you should definitely also carry out practical tasks. It's all about putting theory into practice. For example, if you are learning the basics of equivalence partitioning or boundary value analysis, then look for exercises where you transfer these concepts yourself. The more you do this, the more the knowledge will become part of your everyday test work.

It's also a good idea to socialise with other testers, whether in study groups or online communities. Exchanging ideas with others is not only motivating, but often also very informative, as different perspectives help you to understand the content even better. In these groups, you can ask questions, discuss and also test your own knowledge – these are valuable building blocks for your exam preparation.

Preparation will be a lot easier if you have the right tools at hand. There are a variety of resources available to help you get the most out of your study time. A good place to start is the official material that covers the entire syllabus. There are also accompanying books that give you the theoretical foundation you need to build on.

But theory alone is often not enough. This is where exam simulators come into play, helping you to familiarise yourself with the structure of the exam. These simulators not only give you a feel for the type of questions, but also help you practise time management – a point that is often underestimated in the exam situation. Especially in the area of multiple-choice questions, the experience of having solved similar tasks in advance can be an enormous relief.

Many training providers such as trendig offer you accredited training courses that are precisely tailored to the ISTQB exam in addition to mock exams. These training courses are particularly useful if you find it difficult to organise yourself alone or if you would like to be guided by an experienced trainer. They teach the relevant topics in a structured way, address the exam requirements and give you useful tips on how to best master the exam.

Another tip is to use online communities, such as special forums or groups on LinkedIn. There you can ask questions, network with other examinees and get valuable tips from testers who have already successfully completed the exam. Sharing ideas in these networks can help you to clear up any minor uncertainties and give you new ideas for your preparation.

When preparing for exams, there are a number of traps that many people fall into. One of the most common mistakes is misunderstanding the weighting of the topics. In the ISTQB syllabus, some topics are more important than others. Many make the mistake of getting too lost in rare topics and neglecting the core content. A good tip is to take a close look at the exam structure and prioritise the topics that are frequently tested.

The stress factor also plays a major role. Many people tend to put themselves under enormous pressure, which can often lead to a blackout in the exam. Preparation should rather be a process that takes place over a longer period of time, with regular breaks and without the pressure to master everything immediately. Allow yourself a day off to clear your head – this often helps you to internalise the content even better afterwards.

The ISTQB exam is not rocket science if you prepare systematically and purposefully. The right mix of theory, practice and support from suitable resources will ensure that you are relaxed and well prepared for the exam. Remember: mistakes are part of the preparation, but they are avoidable if you know what is important right from the start.

ISTQB certification is more than just a certificate – it is your key to a successful career in software testing. It equips you with the knowledge you need to perform sound testing and the confidence you need to take on responsibility. Whether you are just starting out in the world of software testing or already have experience, ISTQB certification opens up new opportunities, increases your job prospects and sets you apart from others.

With the various certification levels, from Foundation Level to Expert Level, you can choose exactly the path that suits you and your professional goals. Would you like to learn the basics? Then start with the Foundation Level. Or are you looking for a specialised role, for example in the field of test automation? Then the Advanced Level with specialisation as a Test Automation Engineer is just right for you. Finally, if you want to reach the top and really lead the way, then the Expert Level is your goal.

The demand for qualified software testers is high – and with an ISTQB certification you are ideally positioned to succeed in this growing industry. Companies are looking for professionals who work according to international standards, and that is exactly what you will become with an ISTQB certificate. Not only will you create a solid foundation for yourself, but also the basis for continuous professional growth.

The costs for the Advanced Level and Expert Level are higher, depending on the respective modules. If you take the exam with a training provider, there are additional costs for the accompanying training. The best way to find out about the current prices and any discounts for certain training courses or group participation is to contact accredited training providers such as trendig or exam providers such as brightest directly.

ISTQB certification is your proof of in-depth knowledge in the field of software testing. It not only shows that you have the necessary knowledge, but also that you are prepared to work according to international standards. An ISTQB certificate can help you improve your job prospects, as there are many companies that are specifically looking for certified testers. It is also a sign that you are able to understand and implement complex testing processes, which is invaluable in the dynamic world of software testing.

The ISTQB certifications are divided into different levels: The Foundation Level is the entry into the world of software testing and provides basic knowledge. The Advanced Level offers specialisations such as Test Analyst, Technical Test Analyst, Test Manager and Test Automation Engineer. For those who want to reach the top, there is the Expert Level, which teaches in-depth knowledge for developing test strategies and managing large test projects. This structure offers the right certification for every level of knowledge and every career phase. In addition, you can train further in industry or topic-specific content such as automotive tester or in testing AI-based systems in so-called specialist modules.

Yes, the ISTQB Test Manager is a worthwhile certification, especially if you want to move into a management position in the field of software testing. With the Test Manager certification, you will learn how to plan test processes, assess risks and successfully lead test teams. It is aimed at experienced testers who want to develop further and shows employers that you can not only carry out tests, but also strategically manage entire test projects. This makes you a valuable resource for companies that want to ensure their software quality is at the highest level.

A test design technique in the ISTQB context is a method that helps you to systematically design test cases in order to test the fulfilment of software requirements in the best possible way. In the ISTQB, the technical term for this is ‘test design technique’. Examples of test design techniques are equivalence partitioning or boundary value analysis. These techniques help you to systematically find errors and ensure software quality. They are an important part of ISTQB certification as they give you the tools to design tests efficiently and effectively and thus ensure the quality of the product.

Software testing is the process of checking an application for possible errors to ensure that it fulfils the requirements and works as it should. This includes functional tests, which ensure that all features work correctly, and non-functional tests, such as performance or security tests. The testing process should begin during the planning phase of software development and accompanies the entire software development life cycle. The aim is to find errors at an early stage, assess the quality of the product and ensure that user requirements are met. A systematic approach, as taught by the ISTQB standards, is crucial here.
