What is TestAS?

TestAS is an aptitude test specifically designed for foreign applicants from non-EU countries who wish to pursue undergraduate studies at a German university. Its primary purpose is to assess the cognitive abilities that are crucial for academic success. Unlike other exams, TestAS does not require specialized knowledge in specific subjects and does not measure aspects such as personality, motivation, or interests.

The test is available in two formats: paper-based and digital. Test takers can choose the format that suits them best. The test is conducted three times a year, offering flexibility in scheduling.

Benefits of TestAS:

TestAS offers several benefits for both applicants and universities. Firstly, it serves as a significant selection criterion for German universities. By considering TestAS results, universities can identify applicants who possess the intellectual capabilities necessary for their desired field of study. This helps ensure that students are well-suited for the academic demands of their chosen program.

Secondly, TestAS provides test takers with valuable information to make informed decisions about their academic journey. After taking the test, individuals receive a detailed score report that realistically assesses their chances of successfully completing their studies. This information allows them to evaluate their strengths and weaknesses and choose programs that align with their abilities.

Furthermore, TestAS provides a comparative analysis of an individual’s performance in relation to other test takers. This benchmarking allows applicants to gauge their standing and understand how they fare in comparison to their peers. Additionally, by engaging with the test, applicants become familiar with the typical requirements and expectations of their desired course of study, better preparing them for academic challenges.

Paper-based vs. Digital TestAS:

The TestAS is offered in two formats: paper-based and digital. While both formats contain a core test and subject-specific modules, there are some notable differences between them.

The core test is a common component in both formats and assesses general cognitive abilities that are relevant to university-level courses. It evaluates skills such as logical reasoning, analytical thinking, and problem-solving.

In terms of subject-specific modules, the digital TestAS offers a wider range of options compared to the paper-based version. Test takers can choose from six subject-specific modules in the digital format, including Humanities, Cultural Studies and Social Sciences, Engineering, Mathematics, Computer Science and Natural Sciences, Economics, Medicine, and Life Sciences. On the other hand, the paper-based TestAS provides four subject-specific modules: Humanities, Cultural Studies and Social Sciences, Engineering, Mathematics, Computer Science and Natural Sciences, and Economics.

The digital TestAS has the advantage of being optimized for computer processing, which allows for different task types. It also has a shorter duration, lasting approximately 3.5 hours, compared to the paper-based TestAS, which takes around 4.5 hours, including a 30-minute break.

Test takers can choose the format that best suits their preferences and needs. It’s important to note that the skills and abilities measured by both formats are comparable, ensuring a fair evaluation regardless of the chosen format.

TestAS Structure

The TestAS is structured to assess both general cognitive abilities and subject-specific skills. Let’s delve deeper into its components:

Core Test:

The Core Test is an integral part of the TestAS and evaluates general cognitive abilities that are relevant to university-level courses. This section aims to measure skills such as logical reasoning, analytical thinking, and problem-solving abilities. The Core Test provides universities with insights into the test taker’s overall cognitive capabilities.

Subject-Specific Tests:

In addition to the Core Test, the TestAS also includes Subject-Specific Tests that measure abilities specific to particular fields of study. Test takers have the flexibility to choose from various modules based on their intended area of study. The available subject-specific modules are as follows:

  1. Humanities, Cultural Studies, and Social Sciences:

This module focuses on assessing aptitude in fields such as literature, philosophy, history, sociology, and other related disciplines within the humanities and social sciences.

  1. Engineering:

The Engineering module is designed to evaluate test takers’ abilities in engineering-related subjects, including mechanical engineering, electrical engineering, civil engineering, and more.

  1. Mathematics, Computer Science, and Natural Sciences:

This module tests proficiency in mathematical reasoning, computer science, and natural sciences such as physics, chemistry, and biology. It assesses the test takers’ analytical and quantitative skills.

  1. Economics:

The Economics module measures aptitude in the field of economics, including microeconomics, macroeconomics, economic theory, and related subjects.

  1. Medicine (only in digital TestAS):

Exclusively available in the digital TestAS format, the Medicine module evaluates the aptitude of test takers for medical studies. It may cover topics such as biology, anatomy, physiology, and other relevant areas.

  1. Life Sciences (only in digital TestAS):

Also exclusive to the digital TestAS, the Life Sciences module focuses on assessing knowledge and skills related to life sciences, including biology, biochemistry, genetics, and related subjects.

Preparation materials for the TestAS, including sample questions and practice tests, can be accessed on the official TestAS website. These resources allow test takers to familiarize themselves with the structure and content of the exam, enhancing their preparedness for each specific module.

TestAS Test Centers:

TestAS provides licensed test centers worldwide where individuals can take the examination. These centers are equipped with the necessary facilities and resources to ensure a smooth testing experience. To access a comprehensive list of test centers, individuals can visit the official TestAS website. It’s important to note that not all test centers offer both the paper-based and digital formats of the test. Some centers may only provide one format. Therefore, when selecting a test center, it’s essential to check which format is available at that particular location. In cases where there is no test center available in a specific country, individuals can contact the TestAS administration for guidance on alternative arrangements or recommendations.

TestAS Scheduling:

The TestAS is administered three times a year, offering both paper-based and digital formats. It is advisable to regularly visit the official TestAS website to stay informed about the latest test dates and registration deadlines. The website provides a test calendar that includes the upcoming test dates and associated deadlines. By referring to this calendar, individuals can plan their preparation and registration accordingly. It is crucial to adhere to the registration deadlines to secure a spot for the desired test date and format.

Age Limit for TestAS:

There is no specific age limit for taking the TestAS. While the test is primarily aimed at applicants and students planning to pursue their first degree in Germany, individuals of all age groups are welcome to participate. However, it is recommended to take the test during the final year of secondary school or later. This timing ensures that individuals have had sufficient time to develop solid cognitive abilities, which are assessed by the TestAS. By taking the test at a later stage, individuals are more likely to have acquired the necessary skills and knowledge, leading to a more accurate evaluation of their aptitude for higher education. It is important to note that the TestAS focuses on cognitive abilities rather than acquired knowledge, so taking the test at the appropriate stage of academic development is crucial for optimal performance.

TestAS Retakes:

TestAS allows individuals to retake the test as many times as they wish. This flexibility provides an opportunity for test takers to improve their performance and strive for better results. However, it is important to note that TestAS primarily measures cognitive abilities, which are not easily acquired or significantly improved in the short term. Cognitive abilities are developed over time through learning, experience, and intellectual growth. Therefore, it is unlikely that a test taker will achieve significantly higher results on subsequent attempts without substantial efforts to enhance their cognitive skills.

To maximize the chances of improving performance, individuals considering a retake should take advantage of the resources available from the official TestAS website. The website offers valuable information and preparation materials to help test takers familiarize themselves with the test structure, content, and question formats. These resources can assist in developing effective study strategies, enhancing critical thinking skills, and practicing the types of tasks that appear in the TestAS.

Viewing Examination Papers and Results:

After completing the TestAS, individuals have the opportunity to review their examination papers and answers. This valuable service is provided by the TestDaF Institute, which is responsible for the administration and evaluation of the test. To access this service, test takers must submit an application to the TestDaF Institute no later than four weeks after the announcement of the test results.

By accessing their examination papers and answers, individuals gain insights into their performance and can better understand their strengths and areas for improvement. This review process allows test takers to reflect on their strategies, identify any mistakes or misconceptions made during the test, and learn from them. It provides a valuable learning opportunity and can guide future preparation efforts.

Upon receiving the application, the TestDaF Institute will conduct a reevaluation of the individual’s score. This involves carefully reviewing the test materials and considering any additional information provided in the application. Test takers will be notified of the final result, which may confirm the original score or lead to a potential adjustment based on the reevaluation process. This service ensures transparency and fairness in the assessment of the test taker’s performance.

Overall, the opportunity to view examination papers and results add value to the TestAS experience, allowing individuals to gain valuable feedback, learn from their performance, and make informed decisions about their academic endeavors.


TestAS plays a vital role in the admission process for international students aspiring to study at German universities. By assessing cognitive abilities and providing valuable insights, TestAS helps universities identify qualified applicants, enables students to make informed choices, and familiarizes them with course requirements. Whether you opt for the paper-based or digital format, TestAS offers a comprehensive evaluation of your aptitude for academic success in Germany.
