For the upcoming 2012-2013 school year, the CUSD expects everybody to get in. Stocklmeir has boosted its capacity to 8 kindergarten classes x 33 students per class. That's up from the previous total of 5 kindergarten classrooms x 33 students per class. Luckily, they have maintained the classroom sizes to 33 students per class.
Kindergarteners only go to school for half days. That helps because then schools can accomodate the kindergarteners in two sessions - morning and afternoon. (The morning and afternoon sessions overlap for approximately 40-60 minutes.)
The district expects 300 families to register for Stocklmeir. Most likely the numbers will work out because movement occurs. A certain percentage of parents will opt for another neighborhood school, such as Regnart, through open enrollment.
Nevertheless, the Cupertino Union School District will still hold a lottery for Stocklmeir for the reasons mentioned in my other blog post
