When do you register your kid for school?

My babysitter just ditched me for shady reasons and I'm longing for the days when my LO is in pre-k our Parish school. He's three but he's got an October birthday so I had to wait it out a year. I work in a Catholic school myself and the students are already getting their registration packets for next year. I don't want to be waiting list and I want to apply for a scholarship. When do I look into registering for next year?
