Test Development Process

The process of creating a new test involves generating ideas, trying out the test on a sample group, analyzing the results, revising the test based on the analysis, and repeating the tryout and analysis until the test is deemed reliable and valid.

The process of analyzing the individual items (questions) on a test to determine their effectiveness. This involves examining factors such as item difficulty, discrimination, and distractor effectiveness.

A group of test-takers who take a test during the development process to provide data for analysis and revision.

The initial phase of test development where the test developer conceptualizes the purpose, content, and format of the test.

A type of test that is developed without going through rigorous tryouts, item analysis, and revision. These tests may not be as reliable or valid as those that undergo a more thorough development process.

The Asexuality Identification Scale (AIS) is a validated 12-item questionnaire designed to measure asexuality.

The AIS was developed to identify people who experience a lack of sexual attraction, but may not identify as "asexual".

The AIS has been proven to successfully distinguish between asexual and sexual individuals by accurately classifying self-identified asexual individuals and excluding the majority of sexual individuals.

The AIS demonstrates incremental validity, indicating that it's a better predictor of asexuality compared to existing measures of sexual orientation. It provides unique information about asexuality.

The AIS is a reliable and valid instrument for screening for asexuality. It helps address the need for a standardized measure to identify and understand asexuality.

A testing method where the difficulty of test items is adjusted based on the test taker's performance, making it more efficient and accurate.

Occurs when a test is too difficult for test takers, leading to everyone getting low scores. This makes it hard to differentiate between low-performing individuals.

Occurs when a test is too easy for test takers, leading to everyone getting high scores. This makes it hard to differentiate between high-performing individuals.

The practice items in a test are designed to help the test taker understand the testing procedure before starting the actual assessment.

A collection of test questions used in Computerized Adaptive Testing. The item bank is large and diverse to ensure appropriate item difficulty adjustment for each test taker.

A measure of how easy or difficult an individual item is on a test; calculated as the proportion of test-takers who answered it correctly.

An item-difficulty index value of 1 indicates that all test-takers answered the item correctly. It signifies an item that is too easy.

An item-difficulty index value of 0 signifies that no test-taker answered the item correctly. It indicates the item is too hard.

A larger item difficulty index value (closer to 1) indicates an easier item, while a smaller value (closer to 0) indicates a more difficult item.
