Adaptive technology – how it works?





The idea of Computerized Adaptive Testing is based on the IRT (Item Response Theory) theory, a theory of response to a task that uses probabilistic mathematical models to express the relationship between responses to given tasks and the level of knowledge of the tested candidate. Observation of the way our respondents answer questions in traditional tests allowed us to create an original algorithm (IRT Engine) that simultaneously analyses answers to subsequent questions.

Advantages of the CAT solution

Almost endless number of possible question combinations

Our tests are never the same. There are over 47 trillion possible test combinations! Thousands of questions and an intelligent question matching mechanism combined with an adaptive algorithm result in countless test versions.

Much shorter test time, over 50% shorter than the traditional one

Each time the system matches subsequent questions based on the answers to the previous ones. The algorithm is able to determine the level more precisely than in traditional tests on the basis of twice as few questions and thus in a much shorter time.

Greater precision in determining partial (half) levels

The system first determines the approximate baseline level, and then proceeds to ask additional questions to be able to precisely define the sub-level. Additionally, the mechanism takes into account the time factor in the final determination of the result.

Your questions answered – FAQs

TEST.IN is the world's first self-service platform in the subscription model for conducting language placement tests. It is a solution that combines advanced and unique CAT adaptive technology, an assortment of several hundreds of top-quality professional tests in 30 languages, using a database of several thousands of questions developed by our specialists.
General, business, specialized and industry specific tests in 30 languages ​​are available on our platform. Using our technology, knowledge, and experience, we can prepare, on an individual order, a professional assessment in any field of expertise in any language. We can also design a test fully adapted to the specifics of your organization.
All you need to do is complete a short registration form, activate your account, select the testees, and type of tests.
Creating an account is free of charge.
Our general tests use advanced adaptive technology coupled with randomization mechanisms. This technology ensures that each test is different. A single test uses only a few percent of the questions available in our database. It is arguably the most extensive question database ever created in the world.
The CEFR scale (Common European Framework of Reference for Languages) is an international standard for the description of language competencies used by learners, academic units, and employers to determine the level of proficiency in a foreign language. In November 2001, the European Union Council adopted a resolution recommending the use of the CEFR scale to validate language skills.
The written test result in the CEFR scale appears immediately after it has been taken by the indicated person and is visible in the client's panel on the platform.
The result of the oral test will appear within 24 hours of the candidate taking the test. Our language specialist will then assess the oral level and prepare an audit report which will be available in the client's panel on the platform.
Our tests were created by the best language specialists. Adaptive technology ensures that we get the highest possible precision of results. Our online tests check grammar, vocabulary, and written language skills. To define and accurately describe the general level, which also includes the spoken language, we recommend considering a full audit (available in the PLUS package or as a paid option each time).
We are open to individual negotiations within which we can offer flexible forms of billings and find solutions that best meet our clients' expectations. If you would like to receive an individual cooperation proposal tailored to your organization's needs, write to us, and we will undoubtedly find satisfactory solutions.
Yes, on request, it is possible to obtain a certificate confirming the result and date. Certification is only available for candidates taking the written and oral tests.
Yes, we offer to introduce your company's logo on the report cards and any other individual arrangements for clients who decide on a contract that goes beyond the scope of the monthly packages.
For the proper operation of the TEST.IN platform, we recommend the use of Chrome and Firefox web browsers.
In that case, immediately report it to us via the built-in chat with the candidate's email address, the test will be restarted shortly, and the candidate will be able to retake it again.
All you need to do is select the appropriate option of adding users in the "users" tab and select the appropriate role for the new user – "Testin Account Administrator".
