In its own words
What does Tioga say about itself?
We haven’t read Tioga’s website yet. Until we do, the school’s own site is the best place to hear it in its own words.
Over time
Have results changed?
There’s no spring 2025 result to compare with spring 2026: fewer than 11 students tested here that year, so CDE withheld it.

How the California mean was selected
SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.
