The Texas plan for computer services provides services to public school districts through a statewide network of 20 regional Education Service Centers (ESC). Each of the three Multi-Regional Processing Centers (MRPCs) operates a large computer facility providing school district services within from three to eight ESC regions; each of the five Regional Processing Center (RPC) computer facilities provides services to school districts within one ESC region; and Remote Job Entry (RJE) terminals transmit data and instructions from an ESC or a school district to an MRPC where actual processing takes place. Among the computer applications available to school districts are class scheduling, grade reporting, student master files, attendance accounting, test scoring, payroll, financial accounting, tax accounting, and personnel accounting. This booklet contains information about the objectives and financing of the plan, and tables that show for the MRPCs and the RPCs the personnel, participation in the different services offered, hardware information, and the 1977-78 budget. A directory lists the statewide advisory committee for computer services and education service center executive directors. (Author/LD)
