Original Research by School Decision on The School of San Juan - Alianza
The School of San Juan - Alianza is a charter school operating under the Puerto Rico Department of Education, serving students from prekindergarten through twelfth grade. It sits in the Villa Andalucia neighborhood of San Juan, Puerto Rico's capital and most populous municipality. The school serves a moderate enrollment spread across all grade levels, with relatively even distribution from early childhood through the upper elementary years, thinning somewhat in the high school grades. A very large share of its students qualify for free or reduced-price lunch, and the student body is almost entirely Hispanic, reflecting the broader demographics of San Juan and Puerto Rico.
San Juan itself is a complex, multi-district capital. Publicly reported descriptions portray it as a blend of residential, commercial, government, and tourism zones. Old San Juan is the historic and civic core, defined by cobblestone streets and colonial-era plazas. Hato Rey functions as the financial and business hub. Santurce is an active commercial and cultural corridor. Condado serves as a resort and hotel zone. The municipality is large, spanning many barrios, and much of daily life outside the historic core depends on cars rather than walkable street networks. The city anchors Puerto Rico's government, hosting all three branches, and its economy runs on public-sector employment, tourism, the maritime port, and financial services concentrated in Hato Rey. Civic landmarks include the San Juan National Historic Site with its Spanish-era fortifications, the convention center, and the bay and lagoon system. The city's population has been declining, a trend visible between recent census counts and current estimates, and the broader metropolitan area holds a large portion of the island's residents.
For families considering this school, the available data describes a setting but stops well short of a full academic picture. State assessment results were not available, so there is no way to characterize how students perform on standardized tests relative to expectations or neighboring schools. Multi-year academic trend data was also absent, meaning no direction of change can be described. The school's graduation rate was not reported in the data we received. Information on English learners and students with individualized education programs was missing as well. Program offerings, course access, staffing levels, attendance patterns, and disciplinary records were all absent from the payload. A parent looking into this school would need to ask the school directly for current performance data, graduation outcomes, and details about what academic and support programs it offers.
What can be said is that this is a charter school offering an uncommon full-grade continuum from prekindergarten through senior year, which gives families the possibility of keeping a child in one school community across the entire K-12 span. The grade distribution is fairly even in the early and middle grades, with smaller cohorts in the upper high school years, which may reflect attrition, transfers, or a smaller entering high school class. Whether that pattern affects program depth at the high school level is something a parent would want to ask about, since course offerings and extracurricular options often depend on cohort size.
We looked for recent parent-relevant changes at the Puerto Rico Department of Education level but found little specific information, so we left that out rather than guess. We also searched for a neighbor comparison set to position this school against nearby charter or district schools, but no such comparison was provided.
What remains is a school serving a largely low-income, predominantly Hispanic student population in a full PK-12 charter setting within Puerto Rico's capital. The academic record is not visible in the data we have. Families drawn to the continuity of a single school from early childhood through graduation, or to the charter model within the Puerto Rico public system, should treat this as a starting point and seek the school directly for the performance, program, and support details that the available data does not carry.
