I agree that Sumac’s 50/50 Spanish–English immersion model is often not enough to achieve true Spanish fluency without outside support. That said, this is true of most foreign language programs. Language acquisition requires structure, consistency, and dedication beyond the classroom. Families choose Sumac for Spanish immersion, not for advanced STEM, and some parent complaints seem to overlook that. If a family’s priority is accelerated math or science, a magnet program or supplemental coursework is a more appropriate option.My main concern with Sumac is not the language model, but the academic culture shaped by leadership. While there are some genuinely excellent and dedicated teachers, the overall approach appears to discourage differentiation. Academically strong students are often kept at an average level rather than being challenged through enrichment or individualized assignments. This creates an environment where uniformity is prioritized over growth.Having two children makes this contrast especially clear. One attended a school outside of LVUSD and is confident, academically engaged, and appropriately challenged. My other child, who is actually stronger in math and science, is rarely recognized or challenged. Instead, there are frequent reprimands, including in Spanish, despite a lack of structural support, clear expectations, instructional notes, or consistent communication from teachers. I do not receive feedback directly. I only learn of these issues through my child and remarks made in class.This is particularly disappointing because the potential is there. Sumac works well for ESL students and for families who already speak Spanish at home. However, for native English speakers, especially academically advanced students, the lack of differentiation, limited transparency, and inconsistent support significantly limit progress. My concern is not with individual teachers, but with a system that values leveling students over helping them excel.Sumac may be a good fit for some families, but parents should enter with realistic expectations. Spanish exposure is the program’s strength. Academic acceleration, STEM focus, and individualized challenge are not.
