The Onaga Elementary School community is committed to promoting a physically and emotionally safe environment where students can thrive socially and academically.  In order to accomplish this, there is a Behavior Matrix in place for both students and parents.  These matrices can be found by clicking on the corresponding link.

Morongo Unified School District will continue using the Student Information System again this year.  A Portal for student access allows for students to view their grades, take online assessments, and view attendance.  We are currently asking the parents to work with their children through the Student Portal until the Parent Portal becomes operational.  The Student Portal can be found at  


The 2017-2018 ONES Student Handbook is available online.  The handbook covers school hours, rules and procedures, dress code regulations, and bus rules.  If you have questions about the ONES Student Handbook, please contact Ms. Mery  so that she can help to clarify your questions and concerns.  There are several changes to the Handbook this year.  The Staff of ONES encourages all families to sit down and review the information together.

And you will be successful
