We try to distribute placements as equally as possible across all our deadlines, so an applicant's placement opportunities at the first deadline are ideally the same as at the fifth deadline. In practice, there are external factors that could affect placement opportunities in specific regions.
For the 2018 corps, given testing and hiring timelines, we will not place any fifth deadline (March 2) applicants in the following regions: The Bay Area, California Capital Valley, Los Angeles, and San Diego.
Applying to the first or second deadline does have other advantages, as it allows you more time to prepare for the transition to the corps.
All incoming corps members have to take certification exams and complete their pre-work in advance of summer training. This additional time can also be very helpful as you plan for this transition and a potential move to a new community.
