Our Extended Day Program begins at 7:30 am (8:00 am for preschool) and runs until 6:00 pm. Package rates vary with frequency of participation. Families who qualify for Indexed Tuition can apply their same discounted rate to Extended Day and Summer Camps, up to 50%.

Our commitment to socioeconomic diversity means that not every student is charged the same amount for tuition. Our Indexed Tuition (IT) program is sliding scale, providing access to families who might not otherwise afford an SFS education and making the school more affordable to others. Currently, 29% of our families pay reduced tuition.

Indexed Tuition levels are calculated via Clarity based on assets, income, expenses, and debts. SFS then considers each family’s special circumstances and the school’s available IT funds ($2 million this year).

Through this program, the 2025-26 tuition assistance awards range from $3,600 to $44,300 (8% to 97%). We will apply the same rate that the family receives for tuition to Extended Day and Summer Camps, up to a discount of 50%.

To be considered in the first round of IT decisions, returning families must complete a Clarity application by December 31, 2025. Prospective families must apply by January 9, 2026. The mobile-friendly application takes under 30 minutes and can be saved and resumed at any time.

There is a $60 application fee; you may share your application with other Clarity schools at no extra charge. After submitting, please check your Clarity dashboard for any requests for additional tax documentation.

First priority is returning families, then new families in order to maintain cultural, gender, age, and economic balance across grades.

The IT Committee evaluates all sources of family income, assets, debts, family size, number of students in tuition-charging institutions, and other circumstances. Families are encouraged to apply for external funds (e.g., The Basic Fund, Guardsmen Scholarship) first. Non-working parents’ contributions are recalculated based on SFS guidelines.

Each parent, stepparent, or partner—regardless of legal status—is required to complete a separate Clarity application. Custodial parents should coordinate with non-custodial parents to ensure both complete the process.
