This research was conducted to investigate the validity indices of test item answer key for Watson and Glaser critical thinking test; translated to be compatible with Egyptian society by Jabir and Hindam (1973).

This will be through several indicators: consensus of faculty members in Minia University, as well as some psychometric indicators; such as corrected correlation coefficients between items and total score, discrimination coefficients and number of responses to all alternatives by applying the test to 459 students from Minia University.

Results showed 14 items with indefinite answer key option; according to all indicators.

Results also showed statistically significant differences due to the change of answer key for some items, as of corrected correlation coefficients between items and total score in 73 items.

Findings, also, revealed significant differences related to difficulty and discriminative coefficients, and a number of psychometrically accepted items and test reliability.
