Step2 Accurate Measurement

Proficiency test supported by IRT!

It is a test system backed by testing theories and boasts a high level of measurement precision!

This testing method is based on IRT (Item Response Theory) and measures using a universal scale with the high degree of accuracy. The testing engine as well as item bank development are managed by professional psychometricians , statisticians and native subject matter experts.

CASEC scores the test in a way different from conventional tests that provide "scores based on correct answers" or "total aggregate of allocated points for correct answers" only. For conventional tests, 9 out of 10 questions answered correctly, for example, would result in 90 points. Points are given for the number of correct answers - more points for more correct answers. However, CASEC does not use this scoring method. To understand how CASEC scores, it may be use an 'eyesight test' as an example.

The usual eyesight test first shows a graphic of approximately 0.1 in size symbol at a mid-ranged size. Whether or not the subsequent symbols are bigger or smaller depends on whether the test taker can see the previous symbol or not (ie, correct or incorrect response), Finally, the smallest symbol the test taker can see is converted to a number (eg, 0.7).

CASEC uses the system in that the level of difficulty of the next question changes according to the correct/incorrect answer given by the candidate. If a question is correctly answered, the next question will be more difficult. If it is incorrectly answered, the next question will be easier. Finally, the appropriate level of difficulty is estimated based on the level of difficulty of the questions asked and the patterns derived from the correct and incorrect answers to each question. The estimated level is subsequently converted to a corresponding score. This operation is executed section by section, and the final score is derived by summing up the scores of all the sections.

It is rare but sometimes we get feedback such as "I did not get the correct answer (towards the end) but I actually scored higher (than expected)" or, on the contrary, "my answers were correct but I scored lower points". You would understand why this happen if you have read the above explanation - "CASEC does not score based on the number of correct answers alone."
