Abstract
The study was conducted to determine if students graded by the contract method (experimental group) would retain, for a 5-week period, the knowledge level possessed at the end of a 9-session venereal disease unit and if the contract students would retain as much, or more, knowledge than students graded by the traditional method (control group) . Ss for the grade contract group (n = 27) were drawn from two junior high school health classes and Ss for the traditional grading group ( n = 30) were drawn from two other health classes. Results of the ANOVA tests conducted at the .05 alpha level indicated that 1.) the grade contract students, as well as the traditional grading students, retained the knowledge level possessed at the end of the unit, and that 2.) the contract students did not retain any more, or less, knowledge than the traditional grading students.
