Standardized Testing

CDS uses the Educational Records Bureau Comprehensive Testing Program (CTP 4) to assess efficacy of curriculum and relative student performance. The following graph compares the performance of our students with national and independent school norms over a three-year period, from 2014-2016.

Our students consistently outperform their independent school peers on standardized tests, positioning them for success in applying to the secondary schools of their choice.

Secondary School Placement

Our start-to-finish premier preparation yields graduates who are highly sought after by area secondary schools. According to administrators at these schools, what makes a CDS student unique and coveted are the following characteristics:

  • strong fundamental and 21st century skills
  • self-advocacy
  • high level of executive function
  • well roundedness
  • the ability to pick up on and absorb ideas/concepts that are introduced

      All of the feedback we receive from area secondary schools indicates that we are preparing CDS students well to go on to the schools of their choosing — and that they are not only quickly fitting into these schools but leading others, too.
