Understanding Student-Teacher Ratio

The student-teacher ratio divides total enrollment by the number of full-time equivalent (FTE) teachers.

Formula

Ratio = Total Students / FTE Teachers

Benchmarks

  • Elementary: 15:1 or lower is ideal
  • Secondary: 18:1 or lower
  • National average (U.S.): approximately 16:1

    • Lower ratios generally correlate with better student outcomes, especially in early grades and for at-risk populations.

    हल किया गया उदाहरण

    A school has 450 students and 25 FTE teachers.

    1. Ratio: 450 / 25 = 18.0:1
    2. For 15:1 ratio: ceil(450 / 15) = 30 teachers needed
    3. Teacher gap: 25 - 30 = -5 (shortage of 5)
