Affordability
529 Education Savings Plans
529 Education Savings Plans are a tax-advantaged savings account specifically used for education expenses. While these funds are usually dispersed for college tuition and expenses, most states (including Connecticut) allow families to pay tuition at K-12 private schools up to $10,000 annually. For more information, please contact your tax advisor or an investment professional.
K-12 Education Loans
Some families who don’t qualify for Tuition Assistance choose to explore education loans to help cover tuition costs. While we does not endorse any specific provider, this article offers a helpful overview of available options.

Need-Based Tuition Assistance
Affordability is part of the conversation—and we’re here to help. Our Tuition Assistance Program offers need-based grants ranging from partial to full tuition, helping ensure students from many different financial backgrounds can thrive here. While we strive to meet demonstrated need, assistance does not cover lifestyle choices.
We use the Clarity Application to evaluate financial need based on income, assets, expenses, and debts. The application is mobile-friendly, takes about 30 minutes to complete, and includes a $60 submission fee.

FAQs
All tuition assistance at SLS is awarded based on demonstrated need. SLS does not award merit-based scholarships. Tuition assistance is determined through analysis of a family's financial resources, including income and assets reported in their Financial Aid application and Federal Tax Forms.
Families are asked to complete a Clarity Application and submit supporting Tax Information. A detailed guide to this process can be found below:
Family Application Guide (Espanol)
