Summary:
Yankton School District 63-3 includes five schools—three elementary schools, one middle school, and one high school—in the Yankton area. The elementary schools average 54% proficiency in math, compared with 50% in ELA and 37% in fifth-grade science; the middle and high schools show different strengths by subject. The clearest takeaway is that results vary substantially by school and subject: elementary math is strongest, while elementary science is a notable weakness.
Beadle Elementary stands out, leading the elementary schools in all three current test measures: 58% in ELA, 59% in math, and 49% in fifth-grade science. It is above state results by 9, 15, and 7 percentage points, respectively. At the other end, Lincoln Elementary is below state results in ELA and science by 7 and 11 points, though its math is 4 points above state. Across the three elementary schools, the score spread is 16 points in ELA, 11 in math, and 18 in science. Yankton Middle School is 10 points above state in ELA but 2 points below in math. Yankton High School is above state in all three ACT subjects, by 5 points in math and 6 in science, while its ELA is close to state.
Elementary fifth-grade science declined at all three schools from the prior year, and the group average fell 11 points; Stewart Elementary had the largest drop, 16 points. Other trends differ: middle-school ELA rose 3 points, while the elementary ELA average fell 5. SchoolDigger’s latest statewide percentiles are 68 for Beadle, 30 for Lincoln, 48 for Stewart, 58 for the middle school, and 62 for the high school; each school’s ranking fell from the prior year.
