CAT 2.1

CAT, short for Computerized Adaptive Testing, is a method of assessment that adapts the difficulty level of the questions based on the test taker's ability. It aims to provide a more accurate and efficient way to evaluate knowledge or skills.

CAT starts by administering a medium difficulty question. Based on the response, it adjusts the difficulty level for the subsequent question. If a question is answered correctly, the next question will be slightly more challenging, and vice versa. This adaptive process continues throughout the test.

CAT offers several benefits, such as reduced test duration since fewer questions are needed to assess accurately, individualized assessments that suit each test taker's ability level, and increased measurement precision due to tailored item selection.

CAT is primarily used for educational and certification exams but can potentially be employed in various fields where adaptive testing is advantageous. It is commonly used in disciplines like education, healthcare, psychology, and personnel selection.

CAT exams employ various security measures to prevent cheating. Typically, questions are randomly selected from a large item pool, candidates are presented with different orders of questions, and time limits are imposed. These precautions make cheating difficult.

CAT uses complex algorithms to select questions that can yield the most informative results about the test taker's ability. These algorithms consider various factors such as item difficulty, discrimination, and the estimated ability level of the test taker.

Yes, CAT can provide immediate results due to its adaptive nature. As the difficulty level adjusts according to the test taker's ability, CAT can accurately estimate their performance, allowing for real-time feedback once the test is completed.

While CAT has numerous advantages, it also has some limitations. It requires careful test development and validation processes, as well as sophisticated item banking systems and algorithms. Additionally, familiarity with computer-based testing may be necessary for test takers.

Yes, CAT exams can be taken remotely as long as the necessary technological infrastructure is in place to ensure secure delivery and monitoring of the test. Online proctoring solutions and strict protocols help maintain test integrity during remote administration.

CAT is generally considered more accurate than traditional fixed-form tests as it tailors the questions to each test taker's ability level. This adaptive process allows for precise estimation of a candidate's knowledge or skills within a relatively short testing duration.
