Summary

Gem Prep: Twin Falls is a K-8 public charter school in Twin Falls, Idaho, serving 316 students as its own district, Gem Prep: Twin Falls LLC. The school's standout feature is attendance: chronic absenteeism is just 4.9%, far below the 13.8% statewide rate and dramatically better than nearby schools like Pinecrest Academy Of Idaho (20.4%) and Oregon Trail Elementary School (23.1%). Academically, Gem Prep is above average in math (51.5% vs. 43.1% statewide), about average in English language arts, and slightly below average in science — though middle school results are stronger.

The middle school is a bright spot. Seventh-grade ELA proficiency reaches 64% (statewide: 56.8%), and 8th-grade ELA hits 69.2% (statewide: 54.5%). Eighth-grade science also beats the state by nearly 15 points. A clear weakness shows up in 5th grade, however: math proficiency drops to 30.6% (statewide: 42.2%), science to 29.7%, and ELA to 43.2%. Compared with other local schools, Gem Prep sits in the upper-middle tier. It outpaces Lincoln Elementary School and I B Perrine Elementary School by roughly 25-30 points in math and ELA, and beats fellow K-8 charter Pinecrest Academy Of Idaho in every subject. It trails slightly behind top neighborhood schools like Rock Creek Elementary and Pillar Falls Elementary in some measures, but offers the convenience of a K-8 structure those schools don't.

One trade-off is class size: Gem Prep has the area's highest student-teacher ratio at 22.5-to-1, compared with 18.2 at Rock Creek Elementary and 12.8 at Lincoln Elementary School. Even so, strong scores and exceptional attendance point to a focused culture and engaged families. The school ranks as its own district in the 69th percentile of Idaho districts with a 4-star rating, though its school-level rank slipped from 3 stars to 2 stars recently — more a reflection of other schools improving than a decline in Gem Prep's own performance. For families wanting K-8 continuity with strong middle school academics and standout attendance, Gem Prep is worth a close look.
