Children must be 4 years old by September 1st for Pre-Kindergarten and 5 years old by September 1st for Kindergarten. All applications and registration is done online. Once the school receives your application, our principal will review it to determine next steps. At that point, our registrar may contact you for more information, to schedule a shadow, or to schedule an interview with the student/parents. Once the decision has been made to extend an offer to complete registration, you will receive the offer via email. This will have all the information needed to complete registration. At any time throughout this process, you may email the school registrar, Toni Ortiz at or call 505-892-3221 to ask any outstanding questions you may have.
