What is optimal test design?

Answer 1

optimal test design concerns assembling one or more tests form a pool of items. the tests have to be optimal according to a particular objective and they have to meet one or more constraints

Question 2

What is the aim of adaptive testing?

Answer 2

use as few items as possible to get an indication of a person’s latent variable scores, with an acceptable measurement precision

Question 3

Why is standardization of testing conditions necessary?

Answer 3

it is necessary to guarantee that test scores can be compared

Question 4

Answer 4

1. accomodation is an adaption that does not change the measurement properties of a test
2. modification is an adaption that does change the measurement properties of the test

Question 5

Answer 5

1. test presentation
2. response format
3. test setting
4. testing time
