We’re moving to Baltimore and I don’t have a morah for my son yet. Do I stand a chance of getting him in somewhere?
You can send him to TA or TI at this point and get into their wonderful programs. The preschools are full day and the tuition is just about the same as one of the playgroups. Most people start to send to one of the big schools in the 4 year old year, but we started in the 3s and many many others do also.
TI also offers 3's but only one class as opposed to K and Pre- 1A that are 4 parallel classes. Try them, maybe they still have space. Most people though send to home playgroups for 3's but they are all probably full by now. You have to apply Chanukah time at the latest to get a spot in the good ones.
It might be helpful for you to get onto the Nshei Pickwick group. You can ask there. It is a very big group and there are constantly discussions about playgroups. Email firstname.lastname@example.org and ask to be added.
