From Trinity School’s website:

In mid-September, some families will receive a green postcard stating that we will be contacting them to schedule a tour and interview. Other families will receive a blue postcard stating that we are not yet able to commit to an interview because we are still processing applications.

Who gets the elusive green (for “GO”) kindergarten postcard?  Trinity says:

Our school cares deeply about diversity in the broadest sense of the word, seeking students of varied talents whose geographic, socioeconomic, racial, ethnic, gender, religious, and family backgrounds will enrich our community. We hope to enroll children from a variety of school programs.

In my experience, recipients of green postcards tend to have returned the application on the first day, AND have two or more of the following traits:

  • recognizably diverse families
  • unusually intellectual or academic families
  • well-written, unusual essay
  • from connected preschools
  • famous

So I think Trinity’s stated explanation of their rationale for postcard color choice is quite accurate.
