Tool № 03 · Schools & Child Health

262 schools, 153,466 children.

Every school in SNHN's catchment, from ACARA. The catchment's weighted average ICSEA is 1140 — far above the national mean of 1000 — but the spread runs from low-900s to high-1200s. School-level enrolments are a leading indicator for paediatric load. The sector mix (148 Government / 70 Independent / 44 Catholic) signals where school-based child-health programs reach which kids.

Schools by educational advantage.

Histogram of all 262 schools by ICSEA band of 50 points. National mean is 1,000; SNHN's distribution sits well to the right of national.

§ 02b · Size vs advantage

School enrolment against ICSEA.

Every school as a bubble: x-axis is ICSEA (educational advantage), y-axis is total enrolments, color is sector. The cluster top-right is large, advantaged secondary schools; bottom-left is small specialist or low-ICSEA schools.

§ 02c · LBOTE distribution

How CALD-load is spread across schools.

Each school's LBOTE % bucketed by 10pp band. Tells whether CALD load is concentrated in a few schools or spread evenly across the catchment.

§ 06 · Methodology

Source data and processing:

ACARA School Profile + Location, latest calendar year (2025).
Filtered to SNHN catchment by LGA geo_code (the 9 SNHN LGAs).
Catchment averages for ICSEA, LBOTE %, and Indigenous % are weighted by total enrolments — so a 1,200-student high school carries more weight than a 20-student micro-school.
'Students per teacher' is total enrolments ÷ total teaching staff. Includes part-time / FTE-equivalent reported figures.
ICSEA: ACARA's Index of Community Socio-Educational Advantage. National mean 1,000, SD ≈ 100. SNHN's weighted average of 1140 sits at roughly the 1.4 SD mark.
School locations are ACARA-reported lat/lon; the map projects them into the same SVG viewBox as the LGA boundaries (lon scale corrected for the latitude of SNHN).
