Schools in Zip Code 97623

ZIP code 97623 covers Bonanza, a small rural community in Klamath County, and contains two public schools — Bonanza Elementary School, serving grades K–6 with 206 students, and Bonanza Junior/Senior High School, serving grades 7–12 with 222 students — both part of the Klamath County School District and both located at 31610 Mission St. Together they enroll 428 students. There is no standalone middle school, since grades 7–8 sit inside the junior/senior high, and there are no alternative schools in the ZIP. Both schools serve a very high-poverty population, with free/reduced lunch rates of 92.72% at the elementary and 94.14% at the high school. The district is ranked 78th of 141 in Oregon, at the 45th percentile with 2 stars.

Bonanza Elementary's standout is math: 36.3% of students met proficiency across all grades, above the district (28.3%) and state (32.9%), with 5th-grade math at 40.0% versus 32.4% statewide. Attendance is also better than average — 26.9% chronic absenteeism versus 31.0% district and 33.5% state — though 3rd-grade ELA (27.6%) and 6th-grade ELA (30.8%) lag the state. The school ranks 381 of 709, at the 46th percentile with 2 stars, down from 55th percentile and 3 stars the prior year but still slightly above the district.

Bonanza Junior/Senior High stands out for its 97.0% graduation rate, far above the district (86.7%) and state (83.0%), and for a sharp rank jump from 9th percentile and 0 stars to 40th percentile and 2 stars. Its test scores are the concern: all-grade math is 17.0% and science 13.2%, both well below state, while 7th-grade math is 8.1% versus 33.3% statewide. Chronic absenteeism is 34.6%, worse than both district and state. Science is a shared weakness at both schools, and the 7th–8th grade transition is the most consistent pressure point in this ZIP.
