MBUSD is following the State of California’s Transitional Kindergarten expansion program recommendations for the 2025–2026 school year. Students are eligible to be enrolled in TK if they turn 4 years old by September 1, 2025.

MBUSD will work with families to determine the best grade-level placement for students matriculating from a five-year-old pre-school or Transitional Kindergarten (TK) program (students entering MBUSD at age five or six who have not yet completed a Kindergarten program). Kindergarten placement will be allowed for these students.

Any student, regardless of age, who has completed Kindergarten will be enrolled in Grade 1, unless an appropriately documented Kindergarten Continuation Meeting has resulted in a recommendation for another year of kindergarten. This practice will be updated to align with any  State of California attendance regulation changes.
