Outreach schools are alternative programs that provide personalized education to students choosing not to attend or unable to attend traditional schools. The majority of Outreach students are considered at-risk and Outreach teachers are always looking for new ways to improve at-risk student success - be it graduation rates or achievement. A variety of blended learning models are analyzed for potential use in an Outreach school setting. The Flex Model, Enriched Virtual and variations on these models were found to be the most suitable for the Outreach school setting. Blended learning is found to improve student success more than traditional face-to-face or online learning alone. The blended learning research involving at-risk students does indicate similar results. However, due to the limited research on K-12 at-risk students specifically in blended learning environments, more empirical studies must be performed before robust conclusions can be formed.
