According to the National Center for Education Statistics, the average U.S. class size in 2011-2012 was 21.2 pupils for public elementary schools and 26.8 for public secondary schools. We can do better. At Silicon STEM, we’re committed to the total student experience and the learning process. That’s why we guarantee no more than 16 students per classroom with 1 lead instructor and at least 1 instructional assistant. We believe that an 8:1 ratio is the best way to guarantee a deep understanding and solid results.
