Summary

Patterson International School is an elementary school in Lakewood, Colorado, serving 346 students in grades PK–6 as part of Jefferson County School District No. R-1. The school's state ranking has slipped to 606th out of 943 elementary schools (36th percentile, 2 stars) in the most recent reporting period — the lowest point in a decade and a notable drop from a 66th-percentile ranking in 2015–2016.

The biggest concern for parents is academics. Proficiency rates in the most recent year were 30.0% in English language arts, 26.9% in math, and just 17.1% in 5th-grade science — all well below the district and state averages. Science is especially striking: Patterson posted 60.0% proficiency two years ago and 52.3% last year, so the newest result represents a decline of more than 35 percentage points in a single year. The school's low-income students have experienced the steepest drop, with their statewide ranking falling from the 72nd percentile two years ago to the 16th percentile now. On a more positive note, the school recently earned strong statewide rankings for its Hispanic student subgroup, including a top-7% finish in 2023–2024.

There are genuine bright spots. Chronic absenteeism is 21.8%, better than the district rate of 26.6% and the state rate of 28.4%, and far better than nearby Lasley Elementary School (49.5%) or Rose Stein International Elementary (42.6%). The student–teacher ratio of 15.0 is also favorable. Patterson outperforms its sister international school, Rose Stein, in every major metric. However, it lags behind close neighbors like Kendrick Lakes Elementary School (71st percentile) and Dennison Elementary School, where proficiency exceeds 90%. Patterson sits in the middle of its neighborhood pack — a position that now depends on reversing the steepest decline in its recent history.
