Every campus in Round Rock, Pflugerville and Hutto ISDs ranked by the Texas Education Agency in its annual accountability ratings received a rating of Met Standard or the equivalent for that school. Districts, campuses and charters receive one of three ratings under the accountability system—Met Standard, Met Alternative Standard, or Improvement Required, according to the TEA. In Round Rock ISD, 48 campuses received a ranking of Met Standard, while Success High School received a ranking of Met Alternative Standard. Success is an alternative school and uses its own grading scale. Pflugerville ISD saw all 29 of its campuses receive a rank of Met Standard or, as is the case of Windermere and Delco primary schools, Met Standard-Paired. Windermere and Delco received this ranking because they are primary schools with students in grades kindergarten through second, and they are paired with their third-through-fifth-grade campuses. Eight Hutto ISD campuses also received a rating of Met Standard.
