This investigation studied the impact of male student involvement in selected school activities upon grade-point averages, rates of attendance and college entrance examination scores. The main purpose of this study was to provide data for state officials, school administrators, and school boards as they seek to make decisions concerning the activities program and its place in the educational system. The specific purpose was to determine if involvement in selected school activities had any relationship to the variables grade-point average, attendance, and scores on college entrance examinations. The study was carried out in four large Texas high schools with a total student population of 6,456. Male participants in seven major school activities were randomly selected. This process produced a total sample of 280 male students representing participation in seven activities in four high schools. Each activity was represented by a sample of forty male students. The conclusions were drawn that (1) there is a positive relationship between participation in the activities program by male students and attendance rate, grade-point average, and scores on the Scholastic Aptitude Test and (2) there was no negative relationship between participation in the activities program and the participants' ability to receive a high school education.
