Scientific testing has contributed several things that may be recalled here with profit. First of these, it has given us much more reliable measures of pupils' abilities and accomplishments than by the "old-type" tests we were able to get. Reliability of a test refers to its accuracy in measuring. It means that if a written test shows a pupil to have a score of, say, 85, another pupil's written test of equal ability the same score, and it will give the same score whether marked by one teacher or any other.
