How Triangle Lake Charter School compares with Oregon and U.S. medians
What stands out at Triangle Lake Charter School
Triangle Lake Charter School is a mid-sized charter combined-grade school in Blachly, Oregon, enrolling 416 students.
Class loads run heavy: 23.1:1 is larger than about 91% of Oregon schools and 31% above the 17.6:1 state mean, so each teacher carries more students than is typical.
Economic need runs somewhat below the state's typical profile, with 24.9% of students eligible for free meals.
Enrollment of 416 puts it in the larger third of Oregon schools by headcount.
Its Resource Investment Index trails 96% of the 1,273 Oregon schools with a score on record, one of the lower results on this measure.
Among 198 similarly sized, similarly resourced-need Oregon schools statewide, it ranks #194, in the lower tier once campus size and economic need are matched.
Its student body is predominantly White (87% of enrollment) (diversity index 24/100).
Counselor access is stretched at roughly 416 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 29.6% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Blachly Sd 90 is a single-school charter district, so Triangle Lake Charter School operates independently rather than alongside district-mates.
