What 65 seniors and a 27-year wait tell families about this growing San Jose campus
Quick Answer for Busy Parents
In May 2026, Stratford Preparatory Blackford graduated its first-ever senior class, 65 students, marking the first graduating class in Stratford School’s 27-year history. The campus opened in Fall 2022 as Stratford’s first combined middle and high school site and has grown to more than 900 students in grades 6–12. For families evaluating the school now, this milestone is a useful signal of where Stratford Prep stands: a genuinely new high school program, but one built on a much longer institutional track record in earlier grades.
A 27-Year Milestone
Stratford School has run preschool-through-8th-grade programs across the Bay Area since 1999, but it didn’t offer a full high school until Stratford Preparatory Blackford opened in Fall 2022. That means the May 2026 commencement wasn’t just a first for one campus; it was the first time in the company’s 27-year history that any Stratford school produced high school graduates. The scale of that first class, 65 seniors from a campus that started with a single Grade 9 cohort in 2022, reflects rapid growth over a compressed four-year window.
Why It Took This Long
Building a full high school program from scratch, rather than simply extending an existing K-8 school upward, meant Stratford had to develop a Grades 9–12 curriculum, hire high school faculty, and build out facilities like labs and a theater before it could welcome its first freshman class, which is part of why the first diploma didn’t arrive until 2026.
| Metric | Detail |
| Campus Opened | Fall 2022 |
| First Graduating Class | May 2026, 65 seniors |
| Enrollment Growth | Single Grade 9 cohort (2022) to 900+ students, Grades 6–12 (2026) |
| AP Exam Performance | Average score of 4.2; 101 AP Scholar award recipients |
What the Inaugural Class Achieved
By the time they graduated, Stratford Prep’s first class had access to more than 25 AP courses and at least 8 Stratford Advanced Studies (SAS) courses, positioning the school’s academic offerings on par with far more established campuses despite its short history. Recent students posted an average AP exam score of 4.2, and 101 students earned AP Scholar awards, results that suggest the school’s rapid buildout didn’t come at the cost of academic rigor.
What a First Class Means for Prospective Families
A school’s first graduating class is worth paying attention to for a specific reason: it’s the first real evidence of where students actually land after four years, not just what the school promises during a tour. Families considering Stratford Prep now should ask directly about where members of the inaugural class were admitted to college, since that data offers a concrete look at outcomes in a way marketing materials alone can’t.
Balancing Newness Against Rapid Growth
Stratford Prep’s story so far is one of fast, deliberate scaling rather than slow, organic growth, which can appeal to families who want a well-resourced program without decades of tradition, while families who specifically value long institutional history at the high school level should weigh that tradeoff directly.
