I would take Pitzer off your list, your son’s gpa is well below the average acceptance rate and it has a 14% acceptance rate. All my students that have been accepted there had a 3.8 gpa or higher. Same with Santa Clara, they only had 4% of students enrolled with your son’s gpa and in my experience that may mean the people with a hook like athletes. If you go to the website collegedata.com and insert the college’s name and then click on the admission tab you can get the numbers of where your son compares to the overall admitted class.
My nephew went to Chapman. For film production it will be a reach for your son because that major usually requires a higher gpa and test scores that the average admission profile. The Dodge School is very competitive. (By the way be sure to eat at Bruxie’s across from the campus, I love their waffle sandwiches).
Make sure your son has a portfolio of any film work he has done and submit it as part of the slide show on the common app, it will make his application stronger since his gpa is on the low side for film production for some of his schools.
