Can we use Title I funds for LiveSchool?

Yes, if your school is a Title I schoolwide program. Title I funds can support programs that improve the learning environment, including PBIS tools like LiveSchool.

The U.S. Department of Education permits Title I funds for schoolwide work that improves school climate and culture, including PBIS. Its Non-Regulatory Guidance for Student Support and Academic Enrichment Grants says LEAs can use funds to implement schoolwide positive behavioral interventions and supports (source).

Title I exists to improve the academic achievement of students from low-income families. Your case is strongest when you connect LiveSchool to academic outcomes: attendance, classroom engagement and less disruption.
