| 5/14/2011 | student | Teachers do not care about students, and visa verse. The administration is to concerned with the "gang problems" and "drug use" to concentrate on preparing underprivileged children for an increasingly competitive world economy. Treasure Valley Community College does offer students an opportunity to do college level work, so it's not ALL bad. However, the large majority of students are simply concentrating on graduating high school, let alone college. Overall, the community as a whole is NOT doing enough to prepare its youth for the real world. Large systemic changes are required to right this ship. If you are a parent reading this, and considering moving your child to the Ontario school district, DO NOT! -OHS Alumni, 2009. |

| 2/4/2005 | parent | Ontario High School has a great athletic department and the students that my child goes to school with are very friendly. The buling is a little old, but I know that that will not affect the education of my child. |
