I live in New England so cannot answer for Ca. but with our licensing laws, if you're registered you need a minimum of 6 hours approved training workshops yearly, if you're licensed you need more. And that does not include any required trainings for the food program, CPR/First Aid, or Special Services. If you're participating in STARS(similar to QRIS) you might need even more than that, depending on which arenas you're working on. And that is all changing for our state because the regulations are being changed big-time this coming fall.
Are you licensed or registered through your state or legally exempt or what? You need to read through your licensing regulations to see what's needed to keep your current status valid.
