Summary

Castleford School is an alternative public school serving grades PK-12 in the rural town of Castleford, Idaho. With 302 students, the school is part of the Castleford District and is located about 19 miles from the nearest nearby school, Xavier Charter School.

Castleford School has several notable strengths and challenges. On the positive side, the school has maintained strong 4-year graduation rates, ranging from 81% to 100% in recent years, which is higher than the state average of around 80%. However, the school faces some academic hurdles, with test scores on the ISAT exams generally below state averages, particularly in math and science. For example, in 2024-2025, only 37.2% of Castleford students were proficient or better in ISAT Math, compared to the state average of 43.1%. The school also has a higher rate of chronic absenteeism, ranging from 6.4% to 17.1% in recent years, which is above the state average of around 10%.

One key factor that may contribute to Castleford School's academic challenges is the high percentage of students qualifying for free or reduced-price lunch, ranging from 66.23% to 89.84% in recent years. This is significantly higher than the state average and indicates a high level of economic disadvantage among the student population. Interestingly, the nearby Xavier Charter School has significantly higher test scores than Castleford School, particularly in math and English language arts, suggesting that the district may need to examine its curriculum, instructional practices, and support systems to improve student academic performance.

Open Quote I found it unbelievable to see Castleford as a 2 Star school on here especially if you use test scores since it is one of the only schools in our area that has managed to pass AYP every year with a large majority of ESL students in addition to a large percentage of kids from very low income homes.

What your rating does not reflect is the tremendous amount of community involvement there is with this small town school. The local men's club gives scholarships to every single kid that goes on for college or technical/vocational education after they graduate. Many of the high school students are taking dual credit classes with the local community college, College of Southern Idaho.

We can't wait until our twin boys start school here. How can you beat a 12.1 student teacher ratio at a public school no less? Close Quote
