Fee details
Fee details
Application fee - Application fee: USD 50. This application fee is applied to the student's tuition if the student is offered admission and enrolls.
Tuition fees (overview and how they are set) - Aeon School uses a family-based sliding‑scale (Reduced Tuition) model rather than a fixed published tuition by grade. Annual tuition for enrolled students falls within a published range of USD 11,800 to USD 39,500. The final annual tuition for a student is determined by a family's total household income, assets, and the number of children enrolled. This single-family assessment model applies across the school's grades (grades 5–12). - Because tuition is individualized under the sliding scale, the school does not publish fixed per‑grade or per‑term price lists; families receive the specific annual and installment amounts for their household during the admissions/enrollment process.
Tuition — typical billing schedule and payment terms - Standard billing: families are invoiced and may pay by bank transfer (standard option). Credit card payments are accepted for an additional small convenience fee. - Standard payment plan: billed in two installments per year, with each installment due prior to the start of each semester. - Pre‑pay annual plan: families may elect to pay the full annual tuition prior to the start of the school year to receive a discount on their annual tuition. - Monthly payment plan: a monthly payment option is available for an additional small administrative fee; families enroll in the monthly plan at contract/enrollment.
Boarding fees - Not applicable. Aeon School operates as an online private school (grades 5–12); there are no boarding facilities and no boarding fees.
Other charges and typical additional costs - The application fee is the only routinely stated compulsory fee in the admissions information (USD 50, applied to tuition on enrollment). - The school does not publish a mandatory uniform charge or a routine boarding charge. Any optional or incidental costs (for example, external standardized test fees, AP exam fees, course materials, or optional extracurricular costs) would be billed separately or paid by families as applicable; these are not shown as fixed mandatory school fees in the published admissions/tuition materials.
Refund information - The application fee is applied to tuition upon enrollment. There is no detailed, publicly posted multi‑line refund policy visible in the school's published admissions and tuition material; specific refund or withdrawal terms (for example, how refunds are handled after invoice/installation payments or mid‑semester withdrawals) are set at enrollment/contract stage and are communicated to families through the enrollment contract and invoice. The application fee's application toward tuition on enrollment is explicitly stated.
Fee payment options - Accepted payment methods and arrangements include bank transfer (standard invoice payment) and credit card (accepted with a small convenience fee). Families may choose one of the available payment plans (annual pre‑pay, two‑installment semester billing, or monthly plan with a small fee). Specific invoicing and payment instructions are provided to families when an enrollment contract is issued.
Brief note on published detail availability - Aeon publishes a sliding‑scale annual tuition range (USD 11,800–39,500) and an application fee (USD 50). The school does not publish fixed per‑grade or per‑term tariff tables; families receive an individualized annual tuition and the related installment amounts during enrollment. Detailed refund and withdrawal mechanics, any enrollment deposit amount, and itemized mandatory fees beyond the application fee are handled through the enrollment contract and individual billing.
Fee details
Application fee
- New student application fee (per child): USD 75.
One-time and annual school-wide fees
- Enrollment fee (annual, per child): USD 825. - Society membership fee (annual, per family account): USD 150. - Facilities fee (annual, per family account): USD 1,250.
Rebates and sibling discounts
- Loyalty rebate: USD 700 per child after five years of consecutive enrollment; USD 1,200 per child after seven years of consecutive enrollment. - Sibling rebate: 10% off the lower of two tuitions; 20% off the lowest of three (or more) tuitions.
Annual tuition — Mountain View campus (2026/27 school year)
- The published tuition rates on the school pages are stated as annual amounts for each program and grade band. The school notes that annual tuition may be prorated for students who start mid‑year; several annual fees are explicitly non‑prorated. The per‑term amounts below are an arithmetic division of the listed annual tuition by three (3) to provide an illustrative per‑term figure for database display where a per‑term field is required. This per‑term breakdown is an arithmetic inference (annual ÷ 3) and is shown only to provide consistent per‑term entries; the school publishes tuition as annual amounts.
- Example per‑term (Mountain View, Grades 1–4): Annual USD 27,700 → Per term (illustrative) USD 9,233.33 (27,700 ÷ 3). - Example per‑term (San Francisco, Grades 1–4): Annual USD 31,850 → Per term (illustrative) USD 10,616.67 (31,850 ÷ 3).
Billing schedule and payment terms
- The school lists the enrollment, society membership and facilities fees as annual charges (fees will not be prorated). Annual tuition is published by program and grade; the school states that annual tuition might be prorated for mid‑year starts. - Visiting students pay a daily fee and must present payment in full by the first day of the visit; guest (non‑U.S. resident) students must pay tuition in full at enrollment (tuition will be prorated for guest students but annual fees may not be). - The school's bylaws note that membership (required for attendance) may be terminated for non‑payment after a written reminder if fees remain unpaid for 30 days following that reminder.
Boarding fees
- Boarding is not applicable. GISSV operates two day campuses (Mountain View and San Francisco) and does not list boarding or residential options.
Other costs and typical additional charges
- Afternoon/extended‑care program fees (annual rates listed above) apply if enrolled in those programs. - Parents should expect additional, separate costs for items such as spiritwear/uniforms (Spiritwear store), library and school supplies, field trips, exam fees, and optional extracurricular activities. A school Spiritwear/online store and a Library & School Supplies section are part of the school's published program resources. These items are generally billed or purchased separately from tuition.
Refund information
- For summer programs, the school publishes a specific refund schedule (examples: full refund within a short cancellation window after registration; staged refunds with decreasing percentages the closer to camp start date), and summer refunds are processed within business days as noted in the camp policy. Summer camp refund rules and schedules are explicit for camp registration. - For visiting/guest student arrangements, visiting students pay per day and that payment is applied to tuition if they enroll full time; guest students must pay in full at enrollment (the site indicates tuition for guest students will be prorated). - Annual enrollment, society membership and facilities fees are presented as non‑prorated annual charges; the school's published material indicates these annual fees will not be prorated.
Fee payment options
- The school uses an online parent/administration portal for account access and online payments. The school's giving/payments information confirms acceptance of credit card and eCheck (ACH) payments through its secure online payment system; the school also supports payments submitted through the school's parent portals. Historic payment instructions reference the school's online payment portal for one‑time fee payments.
Notes on timing and display for a database
- The listed tuition numbers are the school's published annual rates for the 2026/27 school year for each campus and program. The school states some fees will not be prorated while annual tuition may be prorated for delayed starts; guest students and visiting students have distinct payment requirements. Use the annual figures as the authoritative amounts and the per‑term figures above only as an arithmetic, illustrative division (annual ÷ 3) if a per‑term field is required by your database.

Scholarships
The school offers need-based financial aid for students entering grades K through 12. A professional third-party reviewer assesses household income/assets and each family's ability to pay. The school makes every effort to meet demonstrated need of admitted or enrolled financial aid applicants, but resources are not always sufficient. Applicants are encouraged to apply; however, there is no guarantee that aid will be fulfilled or that it will be fulfilled at the level requested. Because of high demand and deadlines, all documents must be submitted by the prescribed deadlines for returning and new students. Currently enrolled families must be up-to-date on tuition payments to be eligible. Aid decisions are communicated before enrollment, and all information is kept confidential. New students must submit a school application before financial aid is considered, and contact admissions for an access code. The next financial aid application period is for the 2026-2027 school year, with award decisions by April 30, 2026, and the school must receive all required enrollment documents beforehand. To apply, families use the Clarity platform; steps include starting the application, adding the school to the entry, entering financial information, paying a $65 Clarity fee, and completing the Enhanced Tax Verification if required. International families may need to provide translated income documentation.[source: turn2view0]
