Develop a new method to determine the minimum number of hours per day and per school year to be spent on instructional time.

HB 3260 replaces West Virginia's 180-day school year requirement with a new system based on minimum instructional hours per day and per school year. It sets specific daily minute requirements: 315 minutes for K-5, 330 for grades 6-8, and 345 for grades 9-12, while allowing counties to extend school days by 30 minutes to meet the total hour requirement. The bill permits using "equivalent time" from longer days to cover weather-related closures (up to 5 days) or for teacher professional development (up to 5 additional days), without counting as full school days. This directly affects all public school districts and county boards of education in West Virginia by changing how they structure school calendars and track instructional time.
