If you wish to apply for Professional Development Leave. the PEA contract (2001-2004) states:

Applications for professional development leave shall be made (no later than January 15 of the year prior to the fiscal year in which the leave is proposed) by submitting the prescribed application form to the staff member's supervisor, with a copy to the Director of Human Resources.

The Accounting Services web-site has a downloadable Microsoft Excel spread-sheet (~200Kb) which is that form.
