THIS STUDY WAS CONDUCTED TO (1) DETERMINE WHETHER DIFFERENCES IN TYPING TEST LENGTH, CONTENT, FORMAT, AND TIME LIMIT HAVE ANY EFFECT ON TEST SCORES, AND (2) COMPARE THE RELIABILITY OF 5-MINUTE TYPING TESTS WITH THAT OF 10-MINUTE TESTS. TWO EQUIVALENT FORMS OF THE U.S. EMPLOYMENT SERVICE TYPING TEST AND ONE FORM OF THE U.S. CIVIL SERVICE COMMISSION TYPING TEST WERE USED IN THE STUDY. THE SAMPLE CONSISTED OF 235 APPLICANTS FOR TYPING AND STENOGRAPHIC POSITIONS TESTED IN FOUR LOCAL OFFICES OF THE OHIO STATE EMPLOYMENT SERVICE AND 248 APPLICANTS TESTED IN FOUR LOCAL OFFICES OF THE WASHINGTON STATE EMPLOYMENT SERVICE. SCORES ON 5-MINUTE ADMINISTRATIONS WERE FOUND TO BE COMPARABLE TO THOSE ON 10-MINUTE ADMINISTRATIONS. THE RELIABILITY OF SPEED SCORES WAS FOUND TO BE THE SAME FOR 10-MINUTE TESTS AS FOR 5-MINUTE TESTS, BUT THE RELIABILITY OF ERROR SCORES WAS SOMEWHAT HIGHER FOR 10-MINUTE TESTS THAN FOR 5-MINUTE TESTS. NO SIGNIFICANT DIFFERENCES WERE FOUND BETWEEN THESE TESTS IN EITHER SPEED SCORES OR ERROR SCORES. (PS)
