Item evaluation in a civil service examination

Abstract

Among important attributes of a test item are (1) validity, (2) reliability, (3) uniqueness, (4) correctness of key response. Correctness of a key response should be judged by a person of superior intelligence who is well informed on the subject tested. An examination has serious flaws as a criterion measure unless validated. The worth of a given test item may be determined by the use of the biserial correlation coefficient.
