What could help you in your decision on the best and least expensive school is the fact that Oakdale Christian Academy has been judged by TheBestSchools.org to be among the 30 best Christian boarding schools in the US. They only enroll 60 students, so that makes the teacher-student ratio 1:7, as is the national average for boarding schools.
