Relating to the use of average enrollment for purposes of the public school finance system.

HB 683 changes how Texas calculates school funding by replacing "daily attendance" with "average enrollment" in the public school finance system. It requires school districts experiencing a 2% or greater enrollment drop to receive funding based on either the previous year's enrollment (if caused by a military base closure) or 98% of that enrollment (for other declines). The bill also allows adjustments for districts with many migratory students or those affected by disasters like floods. This directly impacts all Texas public school districts in their state funding calculations.
