According to the Fraser Institute's latest survey, the Aldergrove community school is the worst secondary school in Langley and among the worst 50 in the province, while Langley Fine Arts is the best in Langley and among the top 50 secondary schools in all of B.C.
The conservative think tank released its annual Report Card on Secondary Schools in British Columbia and Yukon Sunday.
The Fraser institutes annual report card has been repeatedly condemned as misleading by teachers and left-of-centre politicians who say it is misleading and favors private schools, but the institute insists it is a valid way to measure whether a school is getting better or worse.
There was no significant change in Langley school rankings.
Four of the 10 local secondary schools made the top 50 of 274 B.C. schools rated by the Fraser report card -- Langley Fine Arts ranked 32nd, R E Mountain was number 37, Langley Fundamental was 48 and Walnut Grove Secondary was number 50.
Only one school, the Aldergrove Community Secondary School, was in the bottom 50 of the BC survey, ranking 245 of 274.
Aldergrove has 2.5 times more special needs students than top-ranked Fine Arts, and the average income of Aldergrove Community parents is 78 per cent of Fine Arts parents, the report shows.

Report co-author Peter Cowley, the Fraser Institute director of school performance studies, said the study found overall school performance has improved, noting the percentage of secondary school exams failed in B.C. and the Yukon over the past five years dropped to 8.1 per cent in 2010 from 11.9 per cent in 2006.
And the estimated percentage of grade 10 students who will not complete grade 12 within three years fell to 17.0 per cent in 2010 from 22.0 per cent in 2006.
"This is promising for B.C. and Yukon schools," Cowley said.
