The school district has 3 preschools. There are hoops to jump through and you would have to pay tuition ($225 a month at Santa Cruz Elementary). But, it's an option.
What were the days/times?
He goes to school Mon., Tues., Thurs., and Fri. He is in the afternoon class and it's from 12:15 to 2:45. The morning class is *I think* from 8:15 to 10:45?
Check with the district. They have what they call a "child find" once a month. They look for "normal" (which just means age appropriate in development) kids that would be good influences and good role models for the developmentally delayed kids. Not sure what it all entails, after she told me how much tuition was, I realized I wouldn't be able to afford it for my little one right now so didn't ask any more questions. But she told me that it's done at the district office.
Sorry I'm not more help.
