U.S. Private K-12 Financial Aid, Explained: SSS vs. Clarity, and What Changes for U.S.-Born vs. Mainland Families

Short answer: U.S. private K-12 financial aid is need-based grant money—not a loan, and not repaid. Applications run through two systems: SSS's PFS form (processing fee around $55) or Clarity (submission fee around $60–$65). The two systems do not talk to each other—use whichever system each target school uses. Most San Diego schools share the February 1, 2027 aid deadline with the application deadline, but OLP closes January 5 and St. Augustine January 15. Before filling anything out, ask each school whether international students are even eligible.

This is EdCommGlobal. We clarify one San Diego school-planning or local-support decision at a time—and turn the next step into a practical plan.

"Our child is applying to San Diego private schools, and we hear financial aid is possible. But what are SSS and Clarity? Our income is in China—how do we document it? And can international students apply at all?"

This guide is for families preparing for fall 2027 entry who are considering financial aid. First, what aid actually is; then how the two systems work; then what changes for U.S.-born families and for mainland families.

What financial aid is: three basic facts

First, aid is a grant, not a loan and not a scholarship. Need-based financial aid reduces tuition directly and is not repaid. It is different from a merit scholarship (awarded for grades or talent): the overwhelming majority of K-12 private school funding is need-based, and strong grades do not translate into more aid.

Second, the school decides, not the system. SSS and Clarity are both third-party calculators: they take your income, assets, expenses, and debts, estimate what your family can contribute, and send that estimate to the school. Whether aid is awarded, and how much, is decided by the school's own financial aid committee. The system does not give money; the school does.

Third, aid must be reapplied for every year. An award this year does not renew automatically, and the amount changes if family finances change. Conversely, a family that did not qualify this year can qualify later if finances change significantly.

The two systems: SSS vs. Clarity in practice

The two systems do not interoperate: if a target school uses SSS, file the PFS; if it uses Clarity, file Clarity; if you apply to several schools across both systems, file both. Before starting, check each target school's admissions page for which system it uses—do not guess.

San Diego examples (per each school's admissions page): Parker requires Clarity submission by February 1, 2027; Pacific Ridge also uses Clarity (with Clarity aid webinars on October 27–28); Grauer's aid deadline is February 1, 2027; St. Augustine's aid application opens October 1 and closes January 15; OLP's aid deadline is January 5, 2027. The consortium's general aid deadline is February 1, 2027, but individual schools keep their own dates—do not apply one date to all.

U.S.-born families: income and assets in China, how to document them

For U.S.-born families, the child applies as a domestic student; but with parents' income and assets largely in China, documentation has four practical issues:

1. How to prove income earned in China. Prepare Chinese tax payment certificates, bank statements, and asset certificates, with English translations from a qualified translation provider. Schools need documents they can file—not just documents they can understand.

2. The tax years line up. China and the U.S. both run on calendar tax years, which helps: when a school asks for "the most recent year's tax return," both sides use the same period. If one parent earns in the U.S. and the other in China, submit both sides—not just one.

3. Ask about the currency conversion basis first. Renminbi assets converted to dollars may use the submission-date rate or the school's own uniform basis—ask the admissions or aid office before filling in a number you estimated yourself, because inconsistencies get questioned later.

4. Both parents submit. Under SSS rules, both parents submit information regardless of marital status; Clarity likewise requires a complete household financial picture. Divorced families follow the same rule—do not submit only one side.

Mainland families: F-1 international students, three questions first

If your child applies as an F-1 international student, settle these three questions before touching any form:

1. Are international students eligible at all? Many schools restrict aid to domestic students; some hold a small separate pool for internationals. Before filling anything out, email the admissions office: "Do you offer need-based financial aid to F-1 international students?" An application filed without eligibility is wasted effort.

2. Does applying for aid affect admission? Most K-12 private schools are need-aware (they consider whether a family needs aid when deciding), not need-blind. Policies differ by school: some review admission and aid entirely separately; some, when seats are tight, prefer students who do not need aid. Ask, then decide whether and how to apply.

3. Proof of funds and aid applications are two different things. International enrollment usually requires proof of funds (showing you can pay tuition), which is a visa and enrollment requirement; an aid application asks the school to reduce part of that cost. Do not confuse them: submitting proof of funds does not bar an aid application, and applying for aid does not replace proof of funds.

Our take: five practical rules for applying for aid

1. Figure out what your family can pay before deciding whether to apply. Do not skip applying just to "look wealthy," and do not exaggerate hardship to apply. Aid committees review the complete financial picture; truthful materials are the floor.
2. Deadlines are earlier than you think. Aid deadlines often coincide with application deadlines, and some are earlier (OLP January 5, St. Augustine January 15). Families needing cross-border certificates and translations should start at least a month early.
3. If you apply to several schools, tabulate the systems. Which school uses SSS, which uses Clarity, each deadline, and each school's extra documents—make the table first, then file, so you do not file in the wrong system or miss a deadline.
4. Aid results usually arrive with admission decisions (March). If admission comes with insufficient aid, schools usually give an accept-or-decline window—decide your family's floor in advance: how much reduction makes enrollment work, and what you do below that floor.
5. Do not treat aid as a bargaining chip. Taking school A's aid offer to "negotiate" with school B rarely works at the K-12 level. A genuine change (sudden income loss, major expense) explained in writing to the aid office works better than negotiation.

FAQ

Does financial aid need to be repaid?

No. Need-based financial aid is a grant that reduces tuition directly; it is not a loan. It is different from a merit scholarship (awarded for grades or talent); at the K-12 level, nearly all funding is need-based.

What is the difference between SSS and Clarity, and which should we file?

SSS (run by NAIS) uses the PFS form, costs around $55, and one form goes to many schools. Clarity is a newer platform that can pull tax data automatically from the IRS, costs around $60–$65, and one application can be shared with multiple Clarity schools. The systems do not interoperate: use whichever system each target school uses, and file both if your schools span both.

For a U.S.-born family with income in China, how do we prepare documents?

Prepare Chinese tax payment certificates, bank statements, and asset certificates, with English translations from a qualified provider. Both parents must submit information; if one parent earns in the U.S. and the other in China, submit both sides. Ask the school about the currency conversion basis before filling in numbers.

Can F-1 international students apply for financial aid?

It depends on the school. Many schools restrict aid to domestic students; some hold a separate pool for internationals. Before applying, ask the admissions office whether F-1 students are eligible and whether admission is need-aware.

When are financial aid deadlines?

Most San Diego schools share the February 1, 2027 deadline with applications, but OLP closes January 5 and St. Augustine January 15. Families needing cross-border certificates and translations should start at least a month early.

When are aid decisions announced?

Usually together with admission decisions (March). If admission comes with insufficient aid, schools usually give an accept-or-decline window—decide your family's floor in advance.
