Haggerty vs Martin Luther King Jr.

Martin Luther King Jr. Elementary outranks Haggerty on the statewide scale by a considerable margin — sitting at #2 of 1,791 Massachusetts schools against Haggerty's #16. Both are elite performers, but the gap is real: Martin Luther King Jr. carries an overall rating of 9.9/10 versus Haggerty's 9.3/10, a 0.6-point difference that reflects a sustained performance edge, not a rounding artifact. Families who treat state rank as a proxy for long-run academic outcomes will find that distinction meaningful.

The academic score delta is the sharpest number in this comparison. Martin Luther King Jr. scores 9.8/10 in academics against Haggerty's 8.3/10 — a 1.5-point gap that is the primary driver of the overall rating difference. Growth scores, by contrast, are nearly identical: Haggerty posts a 9.7/10 and Martin Luther King Jr. a 9.9/10, meaning both schools are exceptionally strong at moving students forward year over year. The growth parity tells parents that Haggerty is not coasting on an advantaged intake — it is genuinely accelerating students — but Martin Luther King Jr. does both at a higher absolute level.

On enrollment and staffing, the two schools diverge in a way that cuts both directions. Haggerty serves 229 students with a student-teacher ratio of 7.9:1, one of the lowest ratios you will find in any public elementary school. Martin Luther King Jr. enrolls 328 students at a 10.9:1 ratio — still well below the state average, but meaningfully less intimate. For families who prioritize individualized attention and smaller classroom environments, the three-point ratio difference is a concrete structural advantage at Haggerty.

Both schools serve grades PK through 05 and sit just 2.2 miles apart in Cambridge, making geography an unlikely tiebreaker for most families. Program offerings beyond core grades are not differentiated in the available data; the decision between them comes down to whether a parent weights raw academic achievement and state rank — where Martin Luther King Jr. leads clearly — against the smaller, more teacher-dense environment Haggerty provides.
