CALVET applicants that are required to file income tax can apply (or reapply) as soon as they have filed their 2010 income tax; students that do not file income tax can apply for 2011-2012 CalVet no earlier than April 16 (day after tax filing deadline).
Veteran Services has copies of the new form and instructions. The CCCApply online application for 2011-2012 BOGW will not be available until after Spring Break. However the paper applications are acceptable until then.
If you are applying late for the 2010-2011 year, you can use the CCCApply system now.
