College in high school programs have faced significant challenges in a number of states in recruiting sufficient teachers with the right credentials to teach in a dual enrollment, concurrent enrollment, or early college high school setting. This is particularly true for partnerships that rely upon high school teachers, especially in parts of the country where accreditors have strict requirements around the credentials these high school teachers must hold in order to deliver the college content. This new paper from the College in High School Alliance, National Alliance of Concurrent Enrollment Partnerships (NACEP), and the Midwestern Higher Education Compact (MHEC), developed by lead author Jennifer Zinth of Zinth Consulting LLC, provides the latest best practices, challenges and opportunities for states, colleges, and school districts looking to build a stronger pipeline for concurrent enrollment teachers.
