May Roberts Primary School

Public Grades K-1

Summary

May Roberts Elementary School is a public elementary school located in Ontario, Oregon, serving grades K-6 with a total enrollment of 355 students. The school is part of the Ontario School District 8C, which is ranked 105 out of 140 school districts in Oregon and has a 1-star rating from SchoolDigger.

May Roberts Elementary School consistently ranks in the bottom half of Oregon elementary schools, with a ranking between 487 and 626 out of 706-710 schools over the past 7 years. The school's academic performance, as measured by the percentage of students proficient or better in English Language Arts and Mathematics, is significantly below the state and district averages across all grade levels. For example, in the 2023-2024 school year, only 22.6% of 3rd graders, 18.4% of 4th graders, 33.3% of 5th graders, and 28.4% of 6th graders were proficient or better in English Language Arts, compared to the state averages of 39%, 41.9%, 46.9%, and 40.7%, respectively. The school's performance on student subgroups is mixed, with Hispanic and Migrant students performing relatively better, while White, Male, and Special Education students have consistently ranked in the bottom half or bottom third of Oregon elementary schools in these subgroups.

Despite the school's academic challenges, its spending per student of $14,781 in the 2021-2022 school year is on par with the nearby Aiken Elementary School and Alameda Elementary School, which generally outperform May Roberts Elementary School in academic metrics. Additionally, May Roberts Elementary School has a relatively low student-teacher ratio, ranging from 14.2 to 16.1 over the past three school years, which is comparable to or better than the nearby schools. These factors suggest that the school's academic challenges are not primarily due to a lack of funding or resources, but rather may be related to the high percentage of students from low socioeconomic backgrounds, which is likely a significant contributing factor to the school's overall academic underperformance.
