Many public university systems rely on their own institutional research (IR) offices, in addition to the IR offices from their member institutions, to help conduct the work of the university system. In this chapter, the author illustrates the type of work conducted by system-level IR offices using a nontraditional data source that can be used to inform long-range planning for the system. This study is an update of an earlier one the author completed while serving as the executive director for the Office of Policy Analysis, the system-level IR office for the University System of New Hampshire (USNH). The analysis relies on a data set created by the office from the annual reports produced by the College Board showing profiles of students from the state who had taken the Scholastic Aptitude Test (SAT) for the years 1980 through 2007. An important advantage of the College Board data is that they provide information on the characteristics of only students who have expressed an interest in pursuing a postsecondary education, as compared to either the entire set of high school graduates or only those who enroll in college. The study is broken down into two main sections. The first section demonstrates how the College Board state reports can be used to examine the demand for postsecondary education in general--and for USNH residential campuses in particular--among New Hampshire's high school seniors, and how demand is likely to change in the coming years. The second section uses the College Board reports to look more closely at the characteristics of college-bound seniors in the state and how they have changed over time. These characteristics include demographic factors (gender, race), socioeconomic factors (family income), postsecondary plans (intended major, highest degree), and academic ability and achievement. Collectively, system policymakers could use this information to answer questions about whether New Hampshire high school graduates have an appropriate level of access to postsecondary education, and to identify issues for the university system to address.
