|Equation||(# participants) x (Q: % earning a higher education degree due to the intervention) x ($ additional lifetime earnings of higher education degree vs. high school) x (Causation factor of a college degree on earnings)|
|Explanation||This metric estimates the impact of non-academic student support services for students in postsecondary programs on the likelihood of receiving a postsecondary degree, leading to increased lifetime earnings.|
This metric is based on multifaceted, integrated programs that directly address many of the barriers to academic success faced by low-income and minority students. The program may include the following components: frequent and comprehensive advising, active messaging to students to encourage enrollment following college acceptance, frequent and comprehensive career and employment services, and financial support.
Number of participants: Reported by program.
Q: Percentage earning an associate degree due to the intervention: [0.10] This is estimated by Constellation staff using the following formula:
Student service expenditures per student: Reported by program.
Difference in lifetime earnings between a higher education degree vs. high school equivalence: [$217,000]. This is the weighted average of additional lifetime earnings of associate and bachelor’s degree holders computed using ACS data (U.S. Census, 2017). These benefits are already discounted to present value.
Causation factor of college on earnings: [0.56]. This is the percentage of observed earnings gains caused by a higher education degree. This factor measures the degree to which the observed difference in earnings between types of graduates and non-graduates is causal (WSIPP, 2019).
