At Benchmarking for Good we help nonprofit associations utilize peer-to-peer comparative benchmarking and research to optimize their utilization of resources in support of Mission achievement and sustainability. In a nutshell, we are big advocates of using comparative data to spur reflection and improvement.
A recent analysis of staffing ratios for 75 NAIS member day schools with enrollment of 300-500 students that (a)experienced post Covid enrollment growth and (b)have student retention ratios above the median level, has us scratching our heads in puzzlement. The findings motivate us to want to help these and similar schools dig into the why’s and wherefores of educational staffing patterns and develop best practice norms.
Here is the crux of the potential opportunity: The ratio between students relative to educational (Teaching plus Instructional Support) Full Time Equivalent (FTE) Staff among these schools ranges from a low of 3 students to 1 staff member to a high of 14 students to 1 staff member, with a median ratio of 7 to 1.
Moreover, the lower student to staff ratios do not appear to correlate with observable benefits such as enrollment growth or lower student attrition, which one might anticipate if students were receiving superior educational experiences.

Assuming a salary plus benefits package of $75,000 for a full time staff member, that difference in ratios could amount to millions of dollars in payroll costs for the schools in question. That is a serious difference and warrants a rigorous effort to understand the value of those additional educationally focused staff and, more fundamentally, what an “optimal” student to staff ratio might be for a mid sized dual curriculum, faith based day school– assuming best practice workloads and staff qualifications. .
A PRIME OPPORTUNITY TO APPLY BENCHMARKING ANALYSIS AND RESEARCH
Benchmarking for Good is eager to tackle this issue during its upcoming Spring grant cycle and welcomes regional school associations, federations, and foundations whose members/grantees would benefit from participating to contact Dr. Harry Bloom at harrybloom@benchmarkingforgood.org to discuss potential project parameters and attractive grant opportunities. We eagerly look forward to hearing from you!
