There is a learning support program designed for students with mild to moderate learning disabilities. In the Early Learning Center and Elementary School, the learning support teacher often acts as a third co-teacher in the room. Middle school and high school students may have learning support during the foreign language elective block.

Billing schedule and payment terms - Tuition may be paid quarterly or annually. Tuition is invoiced as follows: - For new students: the 1st quarter (or the quarter in which the student enters) is invoiced at the time of initial registration; subsequent quarters are invoiced approximately one month before the due date. - For returning students: re‑registration and initial payment deadlines are set in the re‑registration schedule (example dates in the schedule show re‑registration forms and a June payment deadline for the 1st quarter/annual option). Subsequent quarter due dates are published on the annual schedule. - Specific quarter due dates shown in the published schedule include (examples for the year shown): 2nd Quarter due November 6; 3rd Quarter due January 29; 4th Quarter due April 23. Failure to pay the 1st quarter by the deadline cancels the reserved place and invoiced amounts remain due. Individual payment plans may be arranged with the Accounts Manager. - Discounts: 3% reduction on tuition paid in full by the published early‑payment deadline (example: on or before June 15 in the schedule) and 3% reduction on the building fee if paid with the annual tuition by that date. Sibling discounts apply: 15% reduction on Tuition & Building Fee for a third concurrently enrolled child, and 25% reduction for a fourth and subsequent concurrently enrolled child (applied to the youngest children). Early payment discounts are not refundable.
Refunds, cancellations, early withdrawal and related policies - The First Quarter fees (Tuition and Building Fee, if applicable) of attendance are owed as a condition of registering or re‑registering and are not refundable under any circumstances. Failure to pay the 1st quarter by the due date results in loss of the child's place while the invoiced amounts remain due. - Late admission (entry during a quarter): the fee to reserve the place is the full quarter's tuition plus the Registration Fee and the full year's Building Fee if applicable. - Early withdrawal: written notification of intent to withdraw must be given by the published deadlines approximately one month before the next quarter's payment date; failure to provide required written notice results in the full next quarter's fees being due. Any attendance during a quarter results in that full quarter's fees being due. Example deadlines from the schedule are Oct 2 (for 2nd quarter), Dec 18 (for 3rd quarter), and Mar 25 (for 4th quarter). - Refunds for early payments (including discounted annual payments) are not provided; early‑payment discounts will not be refunded under any circumstances.

Admissions
CAISL accepts applications year-round with rolling admissions and welcomes new students at any point during the school year. Starting at the beginning of the school year is often ideal, but not essential. The three-step application process is: First Step—Submit Application: an online form, required documents (school records for the last three years, standardized testing results, and any additional reports), and an application fee of 100 Euros; applications are reviewed only when complete. Second Step—Application Review: decisions are made by a team that includes a member of the Admissions Team, the appropriate Principal (Elementary or Secondary), and the Director; space in the grade/program and the student's academic and behavioral records inform the decision; if a class is full, no new enrollments are accepted until a spot opens; the availability of specialized programs (Learning Support, English as an Additional Language, Nursing/Medical care, and the International Baccalaureate Diploma Program) also affects eligibility. Third Step—Enrollment: when a place becomes available, enrollment requires an Enrollment Contract, a Registration Agreement (updated annually in February), copies of valid identification for the student and the parents, billing information, and proof of payment of the required fees; three mandatory fees to secure a place are: a one-time Registration Fee of 600 Euros, a Building Fee of 1,953 Euros per year (payable for the first five years), and one quarter of the annual Tuition (amount varies by grade); details are in the Fee Schedule.
Admissions
Applications are considered throughout the year, and families are invited to visit the campus. The online application is powered by OpenApply, and you create your account by filling out the TASIS Portugal inquiry form. Complete and submit the application for the appropriate grade level; Early Learning Center (Pre-Kindergarten and Kindergarten) ages 3 to 5, with PK1 needing to be 3 by September 1 and toilet trained, PK2 needing to be 4 by September 1, and Kindergarten needing to be 5 by September 1; Elementary is Grades 1–5, Middle School 6–8, and High School 9–12 (with limited entry to 10th grade if coming from an IGCSE program in alignment with the program). Transcripts from the previous year and current year records are requested starting from Grade 1; recommendations from educators are required; submit results of any standardized tests (e.g., MAP, ERB); English Language Development may be required and tested. Interviews or visits are scheduled by contacting Admissions; Early Learning Center candidates will have an assessment with ELC staff (virtual options available). Submit any educational testing or IEPs if applicable. The nonrefundable application fee is €100 (€150 for ELC applicants). Admission decisions for the 2026–2027 school year note that Grades 2–8 are currently full; availability for Grades 3–8 in 2026–2027 is determined after the re-enrollment process; admissions for Kindergarten, Grade 1, Grade 9 (IGCSE), and Grade 11 (IB Diploma Programme) operate on a rolling basis as spaces become available. The school maintains a Wait Pool for full classes; it is not ranked, and completed applications are required for Wait Pool consideration; space is opened as openings arise and requires balancing factors such as gender and language diversity, sibling enrollment, and academic readiness. A Note to Families: being in the Wait Pool should not discourage applications. Re-enrollment for the following year requires a non-refundable €750 Re-Enrollment Fee by February 15; payment of Campus Enhancement Fund (CEF) is required for Kindergarten and higher (CEF amount set annually) and is non-refundable; withdrawal and refund policies apply, and outstanding fees can affect re-enrollment. For questions, contact the Admissions Office.

Waitlist
Waitlist
WAIT POOL: If there is no space in the grade or program or the applicant is eligible but space is not available, the student may be placed in the Wait Pool for the school year; updates will be requested if the family remains interested; it is impossible to predict when space will become available; when space opens, all Wait Pool applicants are reconsidered and offers are made based on the submitted academic/behavioral records. PRIORITY LIST: 1) Current CAISL re-enrolling students; 2) Students whose parents are US Government employees; 3) Students from American or American International Schools; 4) Students from schools whose primary language of instruction is English; 5) Students from bilingual schools or linguistically unable to attend a school whose instruction is in Portuguese; 6) Students from schools whose instruction language is Portuguese.
Waitlist
The Wait Pool is used when classes are full; applications are always welcome, and only completed applications are eligible for Wait Pool consideration. The Wait Pool is not ranked; the Admissions Committee reviews each applicant as openings arise, weighing factors such as gender and language diversity, sibling enrollment, and academic readiness. When space becomes available, a candidate from the Wait Pool may be offered a place, and families are encouraged to contact Admissions for more information or to schedule a campus tour.
