The Texas Education Agency (TEA) and the Southern Regional Education Board (SREB) joined hands in 2005 to enhance dramatically implementation of the "High Schools That Work" ("HSTW") improvement design in the state. Between 2005 and 2010, nearly 50 high schools in five cohorts joined the Texas Enhanced "HSTW" Network to adopt this intensive improvement design. The partnership between SREB and the TEA expanded further in 2009, when the first cohort of middle grades schools joined the Texas "Enhanced Making Middle Grades Work" ("MMGW") Network. These middle grades schools, which feed into Texas Enhanced "HSTW" sites, are implementing "MMGW" Key Practices for preparing students to succeed in rigorous academic courses in high school. As a group, schools in the Enhanced "HSTW" Network are making progress in advancing student achievement. Schools that have been participating in the network since 2005 have made greater gains in the percentage of students meeting standards in English/language arts, mathematics, science and social studies than average gains across the state. Schools that are implementing the "HSTW" and "MMGW" school improvement designs in a reliable way are seeing results and have gained confidence that the designs can and do work. As a result, they are establishing bolder goals that will enable them to make an even greater impact on student performance in the years ahead. This paper takes a closer look at the accomplishments of the following schools: (1) Galena Park High School; (2) South Grand Prairie High School; (3) Diboll High School; (4) Graham High School; (5) Burton High School; (6) The Summit High School Alternative Program of Excellence (APEx); (7) West Orange-Stark High School; (8) Lubbock-Cooper Middle School; (9) Mount Pleasant Junior High School; (10) Southmore Intermediate School; and (11) Mabank Junior High School. Appended are: (1) Schools in the Texas Enhanced HSTW and MMGW Networks; and (2) "HSTW" and "MMGW" Key Practices and Goals for Continuous Improvement. (Contains 17 tables and 5 footnotes.)
