How to read this page

Homeroom does not rank schools. There is no score here, no grade, and no list putting one school above another. Each figure is shown on its own, with the public file it came from named at the bottom of the page.

Beside each figure are the same figures for this school's district and for California. They are there to give a number a size, not to award a verdict: being above or below either one is not by itself good or bad. Both come from the state's own district and statewide rows in the same file. Homeroom does not add schools together to make them, because any such total would quietly leave out the students whose numbers the state withheld.

A blank cell is not a zero, and a withheld number is not a zero either. Those are three different facts, and this page keeps them apart.

What each cell can say

A number
The state published this figure. It is printed exactly as published.
reported as zero
The state published a zero. Nobody was counted, and that is a fact the state recorded, not an empty space.
withheld to protect privacy
The state has this figure and holds it back, because the group is small enough that publishing the count could identify a student. Homeroom leaves it out. It is never filled in and never shown as a zero.
no figure published
The state published nothing here at all. That is different from a zero and different from a figure held back.

The last three columns are not about this school. They count all 10,534 active schools Homeroom holds, so that an empty row here can be read against how often the state publishes that figure at all.

Students by group

These are the groups the state counts, using its own categories. A group with a small number of students is often withheld, which is why so many of these rows say so.

Chronic absenteeism

A student is chronically absent if they missed 10% or more of the days they were expected to attend. The rate below is the state's own figure, counted only from students eligible to be considered: a student enrolled too briefly, or exempt for reasons the state sets, is not part of it. Homeroom does not compute this rate; it is printed exactly as the state published it.

How much of this the state publishes

Coverage is published beside the data on purpose. A page that showed only what exists would read as a complete picture, and it is not one.

What is not on this page yet

Teacher assignment data is not yet published here. California publishes, for each school, how many teaching assignments were held by a teacher with a clear credential matched to what they teach. Homeroom has read that file and confirmed what it contains, and has not yet decided how to publish it, so this page shows no figure about the teachers at this school.

The state dashboard indicators and per-pupil spending are not here yet either. Each one arrives with its own file and its own access date, or it does not arrive.

Where these numbers come from
