Welcome to the TK & Kindergarten Enrollment Page for the 2024-25 School Year!


We are so excited you are interested in our school, and cannot wait to welcome you to our amazing learning community. This page will guide you through the process for enrolling your student for our TK or Kindergarten classes. It is primarily intended for students enrolling at Mattie Washburn Elementary, because Cali Calmécac Language Academy has its own enrollment process. While you will fill out the same information for both schools, Cali has additional enrollment steps. If you are applying at Cali Calmécac Language Academy, filling out this enrollment form does not guarantee admission. Please click here to view Cali’s admission information and requirements.

  • Enrollment for the 2024/2025 school year will open on Monday, January 22, 2024.

    To register for kindergarten, a child must turn 5 years old by September 1, 2024. To register for Transitional Kindergarten, a child must turn 4 years old by September 1, 2024.

    To complete enrollment you must submit the following documents:

    • Proof of your child’s age and identity (county-issued birth certificate or other acceptable identity document).
    • Immunizations records to date. We will review the immunization records and advise you whether additional immunizations will be required before the start of the school year. You do not need to wait until immunizations are complete to submit them with your enrollment documents.
    • Two proof of residency documents showing parent/guardian name and physical address. Acceptable documents include property tax payment receipt; rental/lease contract or payment receipt; utility service (PG&E, Town of Windsor water, garbage, etc.) contract; statement or bill; pay stub; voter registration or correspondence from a government agency.


    You will have the option to upload these enrollment documents when you complete the online enrollment. If you do not upload documents during online enrollment, you may bring them to the school office between the hours of 8:00am and 3:00pm on regular school days. Please note that once you submit your child’s online enrollment you will not be able to access the document upload feature again.  


    Not required at time of TK/Kindergarten enrollment but required before the first day of school:

    • Proof of Physical Exam. Click HERE to access the Physical Exam form to take to your child’s doctor for completion.

    If you are unable to provide the required enrollment documents, your student may qualify for immediate enrollment. Students who are unhoused, staying temporarily in someone else’s home, foster youth or migrant youth may enroll without providing the documents. You must confirm eligibility with school staff.

     Please contact Mattie Washburn at 707-837-7727 with any questions.

    How to Enroll:

    Aeries Online Enrollment allows you to quickly begin the process of registering a new student for school. Student data is entered such as emergency contacts, previous school information and home language. 

    Upon completion, this data is sent electronically to the school.

    To start registering a new student, click the "Enroll a New Student" button below. If you wish to reprint or review student information for a previously enrolled student, click the Login button.  

    You will be prompted to upload a copy of your students' Birth Certificate, two types of Proof of Residency (ex. Water Bill, Utility Bill, Mortgage Statement) and most recent Immunization Record. If you are unable to upload these documents, you will be asked to provide them when you arrive at the school of enrollment. The online process generally takes 20-30 minutes. If you are unable to complete the process once you’ve begun, you can log out and resume the process later.

    If you have any issues registering your new student online, please check that your browser is up to date. We recommend Google Chrome, which you may download here *Google Chrome Download
