Tennessee Higher Education Commission - As introduced, creates the Tennessee Promise completion grant special account in the state treasury for purposes of awarding completion grants to certain Tennessee Promise scholarship students; makes the four-year pilot program established by the commission to award completion grants to certain Tennessee Promise scholarship students a permanent program. - Amends TCA Title 4, Chapter 49; Title 49, Chapter 4 and Title 49, Chapter 7.

SB 686 makes Tennessee's Tennessee Promise completion grants a permanent program, directly affecting students who received Tennessee Promise scholarships and need additional support to complete their degrees. It creates a dedicated state treasury account for these grants, allowing unspent funds to carry forward annually instead of reverting to general funds. The bill specifies that completion grants can be funded from the new special account or unspent funds from another state grant program, with a $250,000 annual cap on funds from the latter source. Starting in 2025-2026, it also requires colleges to assign coaches to participating students and ensures Pell-eligible students can receive up to $1,000 per semester in completion grants.
