School Calendar

The NIS School Calendar Year

The 180-day school year is divided into two semesters (four quarters), starting in mid-August and finishing in mid-June. A semester is roughly half of the school year, usually from August-December and then January-June; a quarter is roughly half of a semester, usually August-October, October-December, January-March, and March-June. Please note that the age cut-off for grade placement for all grades is September 1.

Daily Schedule

NIS is divided into two divisions, the Primary School, which encompasses the ELC Preschool, ELC Kindergarten and Elementary School grades, and the Secondary School, which encompasses the Middle School and High School grades. NIS operates a rotating A-L day schedule, and classes will rotate within that A-L sequence, not a particular day of the week.

• Primary School: The ELC (ELC Preschool and ELC Kindergarten) keep the same hours as the rest of the school. Each day for the Primary school begins at 8:20, and dismissal is at 3:30. The majority of elementary class instruction is self-contained. 
• Secondary School: Secondary students spend the day moving between classes (mostly with their homeroom group), and classes are scheduled on a rotating A-L day schedule, with daily homerooms and weekly, extended homerooms.  Classes start at 8:20, and dismissal is at 3:30.
• Wednesday Dismissal: On Wednesdays, the entire school dismisses early, at 2:00 pm.
