The State Systemic Improvement Plan (SSIP), WV GRADUATION 20/20 was implemented during the 2015-2016 academic school year beginning with 69 schools in 36 counties, representing 59% of West Virginia's high schools. During the 2016-2017 academic year the number of high schools grew to 72 and the cohort included 20 middle schools bringing the total to 92 schools in 41 counties. The success of the program led to the growth in participation during the 2017-2018 academic school year. The number of participating schools grew to 103 schools in 41 counties. The cohort included 74 high schools, 23 middle schools, six (6) elementary schools, and two (2) alternative centers. The 2018-2019 cohort, the largest to date, contained 121 schools in 44 counties and included 78 high schools, 32 middle schools, nine (9) elementary schools, and two (2) alternative schools. The 2019-2020 cohort of 111 schools in 40 counties includes 66 high schools, 35 middle schools, eight (8) elementary schools, and two (2) alternative schools. The implementation model utilized by West Virginia from 2014-2015 to 2017-2018 was to partner with the eight (8) Regional Education Service Agencies (RESAs) to execute the SSIP-WV GRADUATION 20/20. This model was based on eight (8) Regional School Support Specialists (RS[superscript 3]s) who worked directly with local education agencies (LEAs) and schools to implement the frameworks through coaching and technical support. The 2017 WV Legislative Session resulted in a bill which dismantled the RESAs on June 30, 2018, and included an optional provision allowing the establishment of Educational Service Collaboratives (ESCs). After the enactment of this legislation, the West Virginia Department of Education's (WVDE's) Office of Special Education and Student Support (OSESS) developed the West Virginia Results-Driven Priorities (RDP) Program. Starting in 2018-2019, the RDP's central goal is to improve results for students with disabilities by providing funding directly to the LEAs. Phase III, Year 4 of West Virginia's (WV's) State Systemic Improvement Plan has resulted in developing several new partnerships, and expanding the number of districts served by its partner, the Transition Technical Assistance Center (TTAC).
