Carnegie Math Pathways Return on Investment
The Carnegie Math Pathways—Quantway and Statway—for students placing into development mathematics have had notable success in their first implementation. Over 51 percent of Statway students successfully completed the entire pathway, including earning college-level credit in statistics in one year, compared to 6 percent of a baseline comparison group attempting the traditional sequence in a year.
Even when expanding the timeframe for the traditional group to three years, only 20 percent of the entering cohort achieved transfer-level success, again compared to the Statway rate of 51 percent. These results represent a 250 percent increase in one-year success over the conventional approach extended to three years. For the eight colleges starting Quantway in spring 2012, results were just as heartening.
Johnstone finds that Statway and Quantway may very well make money for an institution.
Achieving results like these generated a good deal of interest from institutions and faculty members. But as Rob Johnstone, with the National Center for Inquiry and Improvement, writes in a Carnegie-commissioned Return on Investment (ROI) study, “While programs such as Statway and Quantway may very well demonstrate an impressive improvement in student outcomes, a significant concern still emerges from a college standpoint: Can we afford to do this at scale?” Johnstone finds that Statway and Quantway very well may make money for an institution. For a relatively modest initial investment of upfront costs that very often is less than the costs of boutique programs, Statway and Quantway can be implemented at scale for the entire range of students needing such an alternate approach rather than for the handful of students served by most boutique programs.
Generally these returns on investment are due to the increases in realized tuition and state apportionment funding from subsequent course taking, and Johnstone employs an ROI model that uses a number of inputs that allow a college to customize it to their local situation, including:
- Salaried personnel costs
- Hourly personnel costs
- Other incremental fixed costs for Statway and/or Quantway implementation (e.g.,
- Carnegie subscription fees, travel to a summer forum and winter regional meetings, supplies, recruiting, etc.)
- College tuition
- State-level apportionment funding per FTEs
- Number of students in Statway and/or Quantway at the college, either as a pilot or at scale
- Predicted increase in FTEs from Statway and/or Quantway
When Johnstone studied the six Pathways colleges who were selected to participate in the ROI modeling exercise, he found that even with relatively conservative estimates on downstream FTEs generated by successful Statway and Quantway students, the model generated a positive return on investment with an associated positive net revenue figure every time.
After calculating these incremental net revenue figures using the model noted in Figure 1, Johnstone also calculated a classic ROI rate.
The ROI rates produced by the model, even with reasonably conservative estimates, were all positive, and ranged from 12 percent to 334 percent. Note that even the 12 percent ROI indicates that the college would generate net revenue that is 12 percent higher than the incremental program costs. From industry standards, ROI rates that are above 50 percent (achieved in three of the six sampled colleges) are considered quite high and those over 100 percent (as observed in three of the six) are extremely high.
The ROI suggest that Pathways will be able to achieve 2.5 times the success rate a net revenue gain to colleges.
Taken together, the results of these ROI models are quite positive, Johnstone notes, concluding that in addition to the more important outcome of getting 2.5 times as many students to succeed in transfer-level mathematics in one year as a traditional group did in three years, the ROI models suggest that Statway and Quantway will likely be able to achieve this outcome at a net revenue gain to these colleges.
In addition, Johnstone also modeled other fiscal impacts such as cost per completer, student tuition and books savings, and student wage gains, finding in each case that a successful Statway / Quantway program would positively impact these key fiscal factors. The study found that “if Statway and Quantway can help get students through their community college pathway one year sooner, these students are estimated to register a nearly immediate $24,600 wage gain. Clearly, the catalytic effect of this gain to transform our students’ lives and accelerate their momentum upward on their career path is remarkable.”
