Summary:
Zip code 96130 has two public high schools in the Lassen Union High district, both serving grades 9–12; together they enroll 831 students, with Lassen High enrolling 816 and Credence High 15. The most important finding is that Lassen’s latest reported proficiency was below state levels in all three subjects, while Credence’s test results are unavailable, so the data cannot establish a proficiency leader.
The schools stand out in different ways on graduation and attendance. Lassen’s 95% graduation rate was 7 percentage points above the state’s 88% and 2 points above the district’s 93%. Credence’s graduation rate was 80%, 15 points below Lassen’s. Attendance is a particular concern at Credence: chronic absenteeism was 97%, compared with 24% at Lassen, 27% in the district, and 18% statewide. Credence’s reported dropout rate was 0%, compared with 2% at Lassen and 8% statewide, so its indicators do not all point in the same direction.
Lassen’s test scores weakened between the two reported years, especially in ELA: its score fell from 51% to 33%, while math declined from 17% to 16% and science from 23% to 20%. Its average gap behind the state across the three subjects widened from 9 percentage points to 18. SchoolDigger’s listed ranking for Lassen also fell, from the 53rd percentile in 2023–2024 to the 29th in 2025–2026, and its rating went from 3 stars to 1. The schools differ in size and other context measures: the student-teacher ratio was 20.2 at Lassen and 6.8 at Credence, while their 2024–2025 free/reduced lunch eligible shares were 34% and 67%, respectively; these figures describe differences, not their causes.
