Back-to-school season is already in full swing. As parents and students prepare for the 2019-20 school year, they will notice a few changes at Keller and Northwest ISD schools. Students who ride KISD buses will be served by a new provider. Texas Central School Bus will bring a new fleet of vehicles to the district. The company will also provide a mobile app that allows parents to track buses in real time. The app is expected to launch later this fall. As a certified District of Innovation, NISD is adjusting the start and end dates of its 2019-20 school year. The district of innovation concept, which was passed by the Texas Legislature in 2015, replaces the state’s requirement of 180 days of instruction to a requirement of 75,600 minutes of instruction. The flexibility allows NISD to adjust the length of its school days, early release days and professional learning days to best serve its community.
