My older son went here, and it used to be better. The teachers have turned over completely and there are many very young ones. It's still a good school, but I will be watching closely this year. I have a first grader.
My children attended Otsego for two years. I found the academic rigor to be high, but more importantly, the standards the district sets for the quality of their teachers is also high. The curriculum is challenging and stimulating, and taught through many interesting, hands on experiences. My older son often commented how his teachers made the learning fun. The only criticism I had was that they overdid the practice testing for the standardized tests -- at the expense of learning a wider variety of topics in a subject. This was done more for the district's image than for the students. But I would be happy to have my children attend this school nonetheless, as they received a fine education in a disciplined environment and enjoyed the experience to boot!
