By the Sub Concierge team · Updated September 30, 2026
Chino Valley Unified School District, in California, posts its substitute jobs through Frontline Absence Management (the system many subs still call Aesop). If you're on the sub list here, everything below is about that board: what shows up on it, how it's written, and what it takes to get the jobs you actually want.

Spelling on the board is what counts. A district that writes “ELEM” instead of “Elementary”, or lists a campus under a classified-staff name, will trip up any filter that expects the official name. Copy the names above when you set preferences anywhere.
How Chino Valley Unified School District writes its postings
Postings here look like this (real titles from the board, teacher names removed):

- *ESL Teacher
- *Early Childhood (PREP) Tchr

Grade levels are written into the title, so you can tell a kindergarten day from a fifth-grade day before you open it.
When jobs post in Chino Valley Unified School District
Most postings here appear before the school day starts. Of the 40 postings we've tracked in Chino Valley Unified School District, about 75% first appeared between 4 and 8 AM local time, 18% during the school day, and 8% in the evening or overnight. The single busiest hour was around 7 AM.
100% of those postings were full-day jobs (six hours or more). 90% started by 8 AM.
These numbers come from postings Sub Concierge watched for its members in this district. They describe what we saw, not every job the district ever posted, and they shift with the season.
How to get the jobs you want here
- Get on the preferred lists. Teachers in Chino Valley Unified School District can name preferred subs, and preferred subs see a posting before the rest of the list does. A short note to a teacher after a good day is the highest-return thing you can do.
- Know the board's spelling. School names and titles above are how the district actually writes them. Filters and alerts that don't match the spelling silently miss jobs.
- Decide your rules once. Which schools, which grades, full-day only or not, how much notice you need. Subs who decide in advance say yes in seconds; subs who decide per posting lose the race.
- Cancel cleanly. Frontline tracks cancellations, and districts notice. Take fewer jobs and keep them.
