NASCE Background The POP Score Why NASCE?


The POP Score

The "Percent of the Possible" or POP Score combines each student's rate, frequency, and depth of service into one easy-to-understand score, for each of 9 areas of human need and overall.  The POP is a measurement for understanding the breadth and depth of a student body's total levels of community involvement, and it is what makes the NASCE unique. 

While the formula is complex, the concept is straightforward:

  • A student who is involved in community service but mostly on a "one-shot" basis (e.g. food drives or local clean-up days) is not having as much of an impact as the student who is engaged in service on a weekly basis for a period of time (e.g. a service-learning course or an alternative spring break trip).  Similary, that student is still not as involved as someone who not only performs service on a regular basis but is and continues to be committed to the cause (e.g. mentoring a third grader every saturday for two years, or continuously volunteering for the Red Cross for emergency relief).
  • Thus, students who serve more often and at a higher level of commitment will achieve a higher POP Score.
  • Each student's survey responses are used to generate an individual-level POP Score for each area and overall (students who do no service get a POP score of 0).
  • These POP Scores are then used to assess the institution's overall service contribution in each area of need.
  • In the Final Report, POP scores are used for institutional comparative analysis within each area and across the NASCE sample as a whole.
