GreatSchools Rating
Parent Rating Average
While this school, as with many, has things to work on, it also has many amazing things going for it. I have to disagree with some of the other comments posted about this school, especially the negative ones about the cotaught class. Studies have actually shown that this type of teaching is actually beneficial of all ages. The 3/4 cotaught class was one of the best experiences at Northside. They did far more field trips and special projects than any other grade level. My child got to hatch chicken eggs, write her own book, do ceramics, participate in the garden program, learn Spanish, go on 6 feild trips (includingan overnightone!), learn weekly social skills lessons... I could go on and on! Luckily for the nay-sayers, this program is no longer in existence at Northside as one of the amazing teachers moved to the junior high. I am so excited that my child will get to experience her again! There is currently a cotaught tk/k class and those teachers are amazing too! All of the teachers put their heart and soul into what they do at this school! Please ask multiple parents about this school before judging it off of this website- where keyboard warriors like to get on soap boxes. Some people are ridiculous!
