Most rating sites would stop at “37% proficient” and call it done. Mammoth deserves a closer read. The school sits in Mammoth Lakes, where two in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

  • Ask what changes between grade 6 and grade 8 here, and who teaches the older kids.
  • Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
  • Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
  • Ask how the school communicates with families when a child starts to struggle.
  • Ask what a typical day looks like for a new student in the first few weeks.

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

What are Mammoth Middle's CAASPP test scores?

On the 2025 CAASPP Smarter Balanced Assessment, 37.0% of students at Mammoth Middle met or exceeded the state standard in ELA and Math combined, and 12.8% exceeded it. The gap between those numbers matters: 24.2% of students are at the proficiency floor, while 12.8% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 465 student-subject combinations were assessed.

How does Mammoth Middle rank in California?

Mammoth Middle ranks #1,539 among California middle schools by Scope Score, placing it in the 31st percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 6 to grade 8 growth), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.

Is Mammoth Middle getting better or worse?

Based on 2025 CAASPP data, proficiency at Mammoth Middle decreases by 6.4 percentage points from Grade 6 to grade 8 growth. This downward pattern doesn't necessarily mean the school is failing — it can reflect cohort differences, demographic shifts, or curriculum changes. A campus visit and conversation with teachers can reveal what the numbers can't. Growth trajectory is weighted at 15% in the middle Scope Score because it measures what the school does, not just who walks in the door.

What is the attendance and school culture like at Mammoth Middle?

19.0% of students at Mammoth Middle are chronically absent (missing 10% or more of school days), compared to the California average of 18.5%. The suspension rate is 6.2%. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
