[1] Anchor test is one type of psychological assessment tool to measure an individual's knowledge or cognitive ability by testing the same areas in different ways.
In psychometrics, to develop assessment tools that are reliable for testing certain skills and abilities are what most Psychometricists are interested in.
Compared with traditional tests in both education and psychology, anchor tests are intended to find out what an individual is able to do rather than what an individual is unable to do.
A study examined that higher anchor test to total test correlation leads to better equating .
It thus implies that an anchor test with items of medium difficulty (miditest) may lead to better equating than an Anchor test of lesser difficulty (minitest).
