Summary

River Islands Technology Academy II (RITA II) is a well-regarded K-8 charter school serving 954 students in Lathrop, CA, consistently earning a 4-star rating and outperforming state averages in English and Math.

Academically, RITA II stands out in the area, with proficiency rates in English (65.51%) and Math (55.43%) that are significantly higher than most nearby traditional public schools like Lathrop Elementary or Mossdale Elementary. Its closest peers in performance are other local charter schools, EPIC Academy and NextGeneration STEAM Academy. The school also maintains better student attendance (14.5% chronic absenteeism) than many neighbors and achieves these strong results with a lower per-student spending rate than schools such as Banta Elementary.

Looking at student groups, RITA II shows notable strengths in supporting English Language Learners and students in Special Education. However, test scores show a significant dip in 5th grade, and the school's science scores trail the state average. While its statewide ranking has slightly declined in recent years, attendance has improved. Overall, as part of the River Islands Technology Academy II District, it presents a high-achieving and efficient option compared to many schools in the broader Manteca Unified area.
