Fees
Application fee
- Registration for admission is made through the school's online "Cadastro de Admissão"; no separate, published non‑refundable application fee is shown on the school's public admissions information.
Tuition fees by school year (summary)
- The school does not publish a public, itemised table of tuition rates by year group and term on its general admissions or services pages. A media compilation that lists tuition figures for top schools in the region shows a monthly figure of R$ 4,336 for Instituto GayLussac; this figure is an example of a reported monthly tuition level referenced in outside coverage.
- Because the school does not provide a publicly posted detailed fee table by year group and term, specific per‑year and per‑term values (for Education Infantil, Ensino Fundamental I/II, Ensino Médio and any bilingual program tiers) are not available in a single published schedule on the school's public pages.
Billing schedule and payment terms
- Payments for charged services and special programmes (for example, recovery programmes and other optional services) are processed via boletos bancários. Billing for optional services is issued and payable by boleto. Specific billing dates, due dates and any early‑payment terms or discounts are set administratively and communicated to enrolled families.
Boarding fees (if applicable)
- The Instituto GayLussac operates as a day school (separate addresses listed for Educação Infantil and Ensino Fundamental/Médio) and does not operate an internato/boarding programme; therefore boarding fees are not applicable.
Other costs and routine additional fees
- Uniforms: School uniform is compulsory. Uniform pieces (including winter uniform items) are obtained through named local suppliers and the cost of uniform items is borne by the family; replacement items purchased by the school are charged to the family.
- School materials: Families are responsible for providing the required school materials; delivery of material before the start of the year and gradual provision in the first week is specified in school guidance. Some specific items and schedules are organised at the start of the year and families must supply the required materials.
- Extracurricular / after‑school activities: The school runs a Club of Culture and Sports and a range of after‑school activities; thematic clubs are offered in the contraturno and the school lists some clubs that are provided free of charge, while some paid CCE activities and external vendors may charge separately. Costs for specific after‑school activities and sports are determined per activity and communicated to families.
- Other administrative fees: The school's internal regulations reference that costs for certain optional academic services (for example, recovery programmes or special registrations) will be disclosed when applicable and paid by boleto. Specific one‑off administrative fees (enrolment/registration, document issuance, late payment penalties, etc.) are managed by the school's administrative office; explicit amounts are not published in a single public fee table.
Refund and cancellation terms
- Historical contract language that was flagged by consumer protection authorities included a provision retaining 30% of the value of the first monthly installment if cancellation occurred before the start of the academic period, with no refund after classes started. This contractual clause was the subject of administrative scrutiny. Families should note that enrolment contracts may include retention or cancellation terms.
Fee payment options
- The school uses boleto bancário as a method for collection of programme and service charges; the school's rules identify boleto as the payment instrument for charged services. Specific acceptance of credit‑card, bank transfer, PIX or other electronic payment methods is not published in a single public schedule; available payment channels and instalment options are handled by the school's billing office at enrolment or invoicing.
Practical notes for parents (factual)
- No public, itemised fee schedule for the 2026/27 academic year is posted in the school's general admissions and services pages; outside media lists include example monthly figures such as R$ 4,336.
- Uniforms, regular school materials and certain optional activities or academic recovery programmes are additional family expenses and are billed through the school's normal invoicing procedures (boletos).
- Boarding is not offered and no boarding fees apply.
