Summary

Alder Grove Charter School 2 is a K-12 alternative charter school serving 481 students in Eureka, CA, operating within its own Alder Grove Charter School 2 District and notable for its exceptionally low student absenteeism.

The school's standout strength is its near-perfect attendance, with a chronic absenteeism rate of only 0.6%, which is dramatically lower than the state average and nearby schools like Glen Paul (56.1%). It also maintains strong graduation rates, though there was a recent dip to 91.1%, and performs relatively well in science, often meeting or exceeding state averages. However, the school faces a significant challenge in mathematics proficiency, where its rates are consistently below the state average and lower than some local alternatives such as Redwood Coast Montessori.

Compared to other alternative schools in the Humboldt County Office of Education area, Alder Grove operates with moderate per-student spending for a relatively large enrollment. This creates an interesting profile: a school that excels at getting students to attend and graduate but is working to improve core academic achievement, particularly in math, highlighting the varied approaches and results among local charter options.

Alder Grove Charter School has provided an outstanding educational environment for my children (I'm a former college professor, and have extremely high academic standards!). With in-person classes as well as flexible options like independent study, online courses, and college courses, the curriculum is uniquely tailored to every student. Students also work one-on-one with an assigned certified teacher for an hour each week, so no one slips through the cracks—my gifted high schooler thrived in this hybrid setting, but I think kids who face more academic struggles would also do quite well at Alder Grove. Highly recommend! Close Quote
