California’s growth results and student groups
State growth model · CDE growth model 2024–25
California's own growth model splits here — the 88th percentile in reading against the 10th in math, among high schools.
Context — never part of the Scope Score
California runs its own growth model — it follows individual children in grades 4 through 8 and compares each one against a prediction from their own prior scores. On that measure this school sits about at the middle of California high schools in reading, and the 10th in math. We show it; we don't score it.
— pts vs expected is scale-score points above or below what California's model predicted for these same children from their own prior-year scores. It is not a percentage and not a percent of anything. A typical California high school lands at −3 in reading, and the middle half of them fall between −13 and +5 — the spread is wide, so read the rank, not the sign. CDE blends two consecutive years into each published figure, so adjacent years share input data and no year-over-year trend can honestly be drawn from them. It covers grades 4-8 only, and it is not part of the Scope Score — we assessed it and left it out: it tracks school demographics roughly three times as strongly as our own growth measure does, and one published year is not enough to test how stable it is.

What should I do next?
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 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.
Questions
Frequently asked questions
Is Altus Schools Mirus a good high school?
Altus Schools Mirus has a Scope Score of 28 out of 100, placing it in the 67th percentile of California alternative high schools and ranked #37 in that group. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. 12.8% of students exceeded the state standard on the 2025 CAASPP assessment, which is 7.0 percentage points below the California average of 19.8%. The Scope Score weights 7 dimensions for high schools: graduation rate (25%), exceeded standard (22%), college/career readiness (20%), met or exceeded (proficient) (18%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Altus Schools Mirus's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 29.1% of students at Altus Schools Mirus met or exceeded the state standard in ELA and Math combined, and 12.8% exceeded it. The gap between those numbers matters: 16.3% of students are at the proficiency floor, while 12.8% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 86 student-subject combinations were assessed.
How does Altus Schools Mirus rank among California alternative schools?
Altus Schools Mirus ranks #37 among California alternative high schools by Scope Score, placing it in the 67th percentile. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), 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.
What is the attendance and school culture like at Altus Schools Mirus?
20.4% of students at Altus Schools Mirus are chronically absent (missing 10% or more of school days), which is better than the California average of 23.1%. The suspension rate is 1.0%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does Altus Schools Mirus compare to other schools in Hesperia?
Altus Schools Mirus scores 28/100 (67th percentile) among California alternative high schools. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. Use the schools in Hesperia page or the map view to compare all high schools nearby.
How does Altus Schools Mirus serve low-income and underrepresented students?
At Altus Schools Mirus in Hesperia, 37.5% of low-income students met or exceeded the ELA standard in 2025, compared to 26.1% district-wide and 38.2% statewide. Altus Schools Mirus outperforms its district average for low-income students by 11.4 percentage points in ELA. Other subgroups: Low-Income students (14.1% Math proficient); Hispanic students (39.3% ELA proficient). Data source: California Department of Education, CAASPP 2024-25. 64 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.

Whole scale-score points above or below what CDE's model predicted for these same children from their own prior-year scores — not a percentage, not a percentile. Statewide a typical school lands near +1 with a spread of about 13 points either side, so read a figure against its group's own typical value, not against zero. Muted rows have fewer than 30 students with a growth score — published by CDE, held back from the narrative sections above because at that size the figure swings about 17 points on its own. “Not categorised” is CDE assigning no band — English Only, Recently Reclassified, and English Learners Only receive a value and no band, for every school in the state. It is not a missing number. Most figures blend two consecutive years, so adjacent published years share input data and no trend line can honestly be drawn across them. A group absent from this table had fewer than 11 students with a growth score and was never published. Grades 4-8 only. None of this enters the Scope Score — it is more strongly correlated with school demographics than our own growth measure, and one published year is not enough to test its reliability.
