5/10GreatSchools RatingParent Rating AverageMarathon high school has a horrible education system I went there for a tew years and couldn't tell you one productive thing I've learned in that school administration also blows some of them have horrible attitude and hardly ever do anything about occurring issues they focus on dress code and attendance rather than the drug issue there which seem to be more important than a little rip in your jeans and other deceitful things that happen there as well they are extremely disorganized when it comes to state testing I would not recommend putting your child in this school they also seem to disregard issues between students until it gets physical and have to do something about it most the time they'd rather sit around because they don't like to write reports the things that they discipline for is absolutely ridiculous your child will get disciplined for a tardy before they'll get disciplined for skipping classes they'll bring it your attention when your child's academics are at risk due to poor attendance.Other Review11mo ago - Stanley Switlik Elementary School
