Assistance is provided directly to teachers and other school personnel who serve individuals with disabilities in Superintendents Regional Study Groups 2 and 3. Staff members participate on various statewide projects that contribute to successful educational outcomes for all students across the Commonwealth. Further, T-TAC Online offers a web community for special educators in Virginia.

VDOE's T-TAC at Old Dominion University is primarily responsible for training and technical assistance in the areas of Early Childhood Special Education/Primary DD (students with developmental delays and disabilities birth through age 9) and individuals with moderate to more significant disabilities (birth through high school). As such, T-TAC ODU also provides training and support to teachers regarding assistive technology that will assist students with communication needs and provide access to the general education curriculum.

Educational professionals residing in Eastern Virginia and who serve school age students with mild/moderate disabilities and students preparing for secondary transition may seek technical assistance through VDOE's T/TAC William & Mary. The T-TAC centers throughout the Commonwealth share the same mission which is to increase the capacity of school personnel, service providers, and families to meet the needs of children and youth with disabilities; and to foster the state improvement goals for personnel development.
