Retention Rate vs Start of Year Enrollment
Formule
## How School Retention Rate is Calculated Retention rate measures the proportion of non-graduating students who return the following year. ### Formula **Retention Rate = Returning Students / (Start Enrollment - Graduates) x 100** **Attrition Rate = 1 - Retention Rate** High retention (above 90%) indicates student and family satisfaction. Attrition drives enrollment decline and budget instability.
Exemple Résolu
500 students at start, 25 graduates, 460 return next year.
- 01Eligible to return: 500 - 25 = 475
- 02Retention rate: 460 / 475 x 100 = 96.8%
- 03Attrition: 475 - 460 = 15 students lost
- 04Attrition rate: 3.2%
Questions Fréquentes
What is a good retention rate?
Above 95% is excellent for K-12. For colleges, 80-90% freshman-to-sophomore retention is strong.
How do I improve retention?
Focus on student engagement, parent communication, academic support, school climate, and addressing individual concerns promptly.
Should transfers be counted separately?
Ideally yes. Track voluntary departures separately from relocations to understand controllable attrition.
