The data story: John M Tobin vs Martin Luther King Jr.
Martin Luther King Jr. Elementary and John M Tobin Elementary sit 0.6 miles apart in Cambridge, Massachusetts, and both serve the same PK–05 grade span — but their state rankings reveal a meaningful performance gap. Martin Luther King Jr. holds the #2 position out of 1,791 schools in Massachusetts, while John M Tobin ranks #27. That is a 25-spot difference in the same state, and it translates to a 0.7-point overall rating gap: Martin Luther King Jr. scores 9.9/10 against John M Tobin's 9.2/10. Both schools rank in the top 2% of Massachusetts elementary schools, but families drawn to the very top tier have a clear answer.
Academically, Martin Luther King Jr. edges out Tobin 9.8 to 9.4 on the academic score — a 0.4-point delta that reflects consistently stronger subject-level proficiency. The growth score separation is wider: Martin Luther King Jr. scores a perfect 9.9/10 on growth versus John M Tobin's 8.9/10, a full point difference. Growth scores measure how much students improve relative to academic peers with similar starting points, so that gap indicates Martin Luther King Jr. students are advancing at a faster rate regardless of where they enter. For families whose child is behind grade level and needs to close a gap — or who is ahead and needs to keep stretching — that 1.0-point growth advantage at Martin Luther King Jr. carries real weight.
