Membership services is a division within ATRS that retains and communicates information to teachers and retirees of the State of Arkansas related to benefit calculations, vesting Status and payout options. ATRS offers a wide variety of options to support most retirement decisions.

Tejas Tech and its associates are responsible for the architecture, implementation, and maintenance of the new membership system for the Arkansas Teachers Retirement System  (ATRS). The new system replaces the hard to maintain software, which involved more than 600 software programs, which were patched together to work as a single system. This new Membership system has been in operation since June 2004.
