Newsweek ranked SEM 8th best in 2006, 2nd in 2007, 4th in 2008 and 2nd in 2009. In the 2005 study, SEM came 6th but TAG was excluded from the survey because of the way it pre-screens students for admission.

Yvonne A. Ewell born September 19, 1926. Died April 27, 1998
DISD superintendent Linus Wright first proposed creating Townview in 1978 as a way to save costs; having a centrally located magnet center would reduce transportation costs. U.S. federal judge Barefoot Sanders, involved in desegregating DISD, supported the plan. Yvonne Ewell and one other DISD administrator were tasked with developing the center, and Ewell helped obtain acres|on}}land in East Oak Cliff. Ewell retired from DISD in 1984.The center was name after her. Because of accomplishments made through out the years in the district An economic downturn in 1987 stymied a DISD real estate scheme to sell Crozier Tech High School, and this in turn prevented the originally planned summer 1987 opening for Townview. As of 1992 the proposed cost estimate for Townview was $30 million. In 1992 Sanders allowed the district to scale back its plans for Townview, but he also ordered it to be completed by 1995.
Laura Miller, then writing for the Dallas Observer, stated that there was a lot of buildup in regards to Townview helping solve racial segregation issues in DISD, and also that there was a sense of sacrifice from landowners in Oak Cliff, many of whom were low income and elderly, who gave up their land for Townview.
As Townview was developed there were controversies over what role the principals of the individual magnets would have relative to that of the head of Townview, as well as designs over the curriculum and instruction of those in the individual magnets.
