What These Numbers Mean

Teacher FTE

Full-Time Equivalent counts part-time teachers proportionally. One full-time teacher = 1.0 FTE; two half-time teachers also = 1.0 FTE. This is the standard federal reporting unit.

Pupil : Teacher ratio

NCES-reported ratio divides total enrollment by teacher FTE. It is NOT the same as average class size — schools with specialists, coaches, and resource teachers will show lower ratios than typical class sizes.

How to read the trend

A falling pupil:teacher ratio (line going down) means more staffing per student — generally a positive signal. A rising line can indicate budget pressure or fast enrollment growth outpacing hiring. Always compare to the US average (dashed grey).

Historical data spans 20202024 from NCES CCD.

Student Support & Wellbeing

Non-teaching staff who support student mental health, physical health, and behavioural needs. Lower pupil-to-staff ratios mean more one-on-one access.

Why these ratios matter

Counselors (ASCA 250:1)

School counselors support academic planning, college & career readiness, and social-emotional wellbeing. The American School Counselor Association recommends no more than 250 students per counselor.

Nurses (NASN 750:1)

School nurses manage chronic conditions, medications, immunisations, and emergencies. The National Association of School Nurses recommends at least 1 full-time nurse per 750 students (more for high-need populations).

Psychologists (NASP 500:1)

School psychologists assess learning & behavioural needs, run mental-health interventions, and coordinate special-education services. NASP recommends 500:1 or lower.

Social workers (SSWAA 250:1)

School social workers bridge home-school relationships, address attendance & trauma, and connect families to community resources. SSWAA recommends 250:1.
