Summary
W. R. Nelson Elementary serves 460 students in grades K–5 in Tustin, within Tustin Unified. In 2025–26, its proficiency rates were below both the state and district in English language arts (ELA), math, and science. The key concern for families is that Nelson’s results remain behind both comparisons in every reported subject.
Math is Nelson’s strongest subject relative to nearby schools and to state and district results, while science is its weakest. Nelson’s proficiency was 32% in math, compared with 38% statewide and 56% in Tustin Unified; its shortfall against the state was smallest in math, at 7 points. In ELA, Nelson scored 38% versus 49% statewide and 64% in the district; in science, it scored 24% versus 36% statewide and 50% in the district. Among nine nearby Tustin Unified K–5 schools, including Nelson, it ranked sixth in ELA and science and seventh in math. Nearby-school averages were 49% in ELA, 48% in math, and 39% in science, putting Nelson 11, 16, and 15 points below those averages, respectively.
Nelson’s scores have risen since 2022–23: ELA gained 9 points, math 9, and science 3. Its state gaps narrowed in ELA and math but widened in science, from 9 points to 12. SchoolDigger’s overall rating improved from the 23rd percentile and 1 star in 2023–24 to the 38th percentile and 2 stars in 2025–26, though Nelson ranked sixth among the nine nearby schools. SchoolDigger’s ranking for Low Socio Economic Status Students rose to the 49th percentile in 2025–26, compared with the school’s overall 38th percentile; its English Language Learner Students ranking was more volatile, falling from the 72nd percentile in 2022–23 to the 14th in 2023–24. As context, 87% of Nelson students were free/reduced lunch eligible in 2024–25, and its 2024–25 student–teacher ratio was 25.5:1—lower than four and higher than three nearby schools. These measures describe context, not causes of achievement results.
