ACT created the "Enrollment Management Trends Report" to provide enrollment managers and other college administrators with information about students' patterns during the college choice process of the 2011 high school graduates who took the ACT[R] test. More than 1.6 million students--roughly half of the graduating class of 2011--took the ACT during high school. Of these students, a little more than 70% enrolled in college the following fall. This report covers such topics as the students' migration patterns, the time in which they first took the ACT, their participation in ACT's Educational Opportunity Service (EOS), and their score-sending behavior. Unless otherwise noted, all information in this report comes from the ACT-tested high school graduating class of 2011. Information in this report--such as the students' background characteristics, time of testing, ACT scores, college preferences, participation in EOS, and college choices--is collected when students register for and take the ACT. Enrollment information for the ACT-tested graduating class comes from the National Student Clearinghouse (NSC) and is supplemented by enrollment information from ACT's Class Profile Service. ACT believes that the information provided in this report will give institutions insight into their current enrollment management practices and offer effective strategies for improvement.
