About Us



COSA is designed to elevate the field of out-of-school time (OST) education and programming as a key to breaking the cycle of multi-generational poverty.

Towards this end, COSA strengthens the OST field via a three-prong approach:

  1. Helping OST programs build organizational capacity,
  2. Conducting high quality research that promotes innovative models, and
  3. Advocating for the field.

How did it begin?

COSA was formed in 2018 as a department of Open Doors, Inc., in partnership with the Ohio Department of Education to provide high quality, ongoing professional development and mentoring support for Expanded Learning Time and Out-of- School Time programs that are recipients of Ohio's 21st CCLC grants.

COSA's goal is to use a multi-tiered approach to increase the skills, competencies, and confidence of 21CCLC grantees across Ohio.

COSA also wants to use its position as a convener among OST programs to help produce stronger OST outcomes and increase collaboration between programs, partners, and the state.
