Summary

Slack Elementary is a small public elementary school located in Ranchester, Wyoming, serving grades K-5 with a total enrollment of just 20 students. It is part of the Sheridan County School District #1, which is ranked 3rd out of 43 districts in Wyoming and has a 5-star rating from SchoolDigger.

Despite its small size, Slack Elementary has seen fluctuating performance over the years, with its statewide ranking ranging from 52nd out of 147 schools in 2023-2024 to 130th out of 149 schools in 2024-2025. The school's proficiency rates in English Language Arts and Mathematics are consistently lower than the district and state averages, particularly in 3rd and 5th grades. Interestingly, Slack Elementary has the highest spending per student among the schools analyzed, ranging from $9,764 to $28,640 per student, and a lower student-teacher ratio compared to the nearby Big Horn Elementary, Tongue River Elementary, and Sheridan County School District #2 schools.

When compared to the surrounding schools, Slack Elementary's academic performance does not seem to be commensurate with the level of investment. The larger schools in the area, with enrollments ranging from 214 to 322 students, tend to have higher proficiency rates in core subjects, despite spending less per student. This suggests that Slack Elementary may need to identify and address the factors contributing to its underperformance in order to better serve the local community.
