The short answer

Most school closure days are known a year ahead: districts publish staff development days, minimum days and breaks on their instructional calendar. Download your district's calendar as soon as it's released, mark every non-instruction day and early dismissal, and book care for them early. For transitional kindergarten, which follows the school day, plan regular afternoon care as well.

Transitional kindergarten

California's transitional kindergarten is free and open to all children who turn four by September 1 of the school year. TK runs on the school calendar and school day, so families who used a full-day preschool before often need care for the afternoon hours and for every school closure day.

A simple plan for the year

  1. Get the calendar. Find your district's instructional calendar on its website as soon as it's adopted.
  2. Mark every gap. Staff development days, minimum days, holidays and breaks.
  3. Book early. Licensed programs with drop-in space fill up on the days every family needs.
  4. Have your child's records ready. Any licensed program will need a complete enrollment file before the first day.
  5. Plan your backup to the backup. Keep a second option for days when your first choice is full.
