Entrance Testing

The purpose of admissions testing is to make certain that our school's academic program is a good match for applying students, and to help guide course placement for Upper School students. A CHS Online Application and Application Fee must be submitted before admissions tests are scheduled.  

If prospective students have taken a standardized test within the past year, please submit a copy to the admissions' office together with school records/transcripts.  In many cases, this will fulfill the requirement and additional testing may not be required. (Please see a partial list of  accepted tests below.)

A private screening appointment can be scheduled through the Admissions Office beginning in January. Depending on the information gained in the process, your child will take one or more of the following screenings:
The Gesell Developmental Screening
Grades One through Four - students applying for these grades usually have not yet taken standardized tests and will be required to schedule testing through the CHS admissions office once an application is submitted.
Stanford Achievement Test (Math and Reading Sections)
Otis Lennon School Ability Test (OLSAT)
  • OLSAT 8 measures cognitive abilities that relate to a student's academic success in school. By assessing a student's verbal, nonverbal, and quantitative ability, OLSAT 8 provides valuable information to enhance the insights gained from traditional achievement tests.
