The NEMSIS Technical Assistance Center (TAC), funded by the Office of EMS at NHTSA, is responsible for assisting state and local EMS entities utilizing a NEMSIS-compliant electronic Patient Care Reporting system (ePCR). Ensuring the accurate application of the NEMSIS standard across the EMS software market has been accomplished through the use of a compliance testing process maintained by the NEMSIS TAC. All entities wishing to develop a field or state-level software solution for collecting, aggregating, and transmitting ePCR information can utilize the compliance testing process free of charge.

To ensure the precision and reliability of data contained in the National EMS data repository, the NEMSIS TAC will not accept data from states collected using a software product that has not passed compliance testing offered by the NEMSIS TAC. The NEMSIS TAC compliance testing process is designed to minimize the time and resource commitment required by software developers to complete the process.
