Summary

Union Mine High is a public high school serving about 1,033 students in grades 9-12 within the El Dorado Union High district in El Dorado, CA, known for its strong graduation rates but facing some academic challenges in specific subjects.

The school excels at ensuring students graduate, with a 98% graduation rate and a very low dropout rate, outperforming or matching many peers like Oak Ridge High and Ponderosa High. However, test scores in math and science are significantly lower than these nearby schools, creating a notable gap between graduation success and subject proficiency. Attendance is also an area for improvement, as chronic absenteeism, though better than pandemic highs, remains higher than at most comparison schools.

Union Mine High serves a more economically diverse population than some neighbors and shows notable strengths in supporting English Language Learners and students in Special Education. While spending per student is relatively high, academic outcomes have gradually declined over the past decade compared to stable or improving schools like Vista del Lago High. The school's performance in English Language Arts is solid, suggesting a foundation to build upon as it works to strengthen its mathematics and science instruction.
