2305 S Water Ave, Portland, OR 97201. The campus sits just south of downtown Portland on the edge of the South Waterfront District, an urban area with multiple play spaces and a garden. The six ISP buildings and four outdoor spaces are on private blocks between Naito Parkway and Harbor Drive. The campus is easily accessible by public transit and is integrated with the surrounding urban environment.

The school comprises Early Childhood and Elementary levels. Early Childhood includes PreK and LowK; Elementary covers Grades 1 through 5.

Independent private IB World School offering preschool through elementary education. It provides language immersion in Chinese, Spanish, and Japanese.

Student Support provides academic and social-emotional support with individualized plans designed by classroom teachers and specialists. The team collaborates with families and does not diagnose or label students; plans may be implemented for 4–6 weeks.

School days begin at 8:00am with arrival allowed up to 30 minutes before. From 8:30am to noon, students participate in morning learning and activities. Lunch and outdoor play occur from noon to 12:45pm, followed by nap or quiet time for younger students; afternoons include art, PE, and music, with library visits.

Application & Enrollment Fees

- Application fee: USD 75 (one-time, non‑refundable) for new applicants.
- Enrollment (acceptance) deposit: USD 500 (one-time, non‑refundable) required with the enrollment contract for new students. Enrollment contracts for new students are mailed in February and the USD 500 deposit must be returned by the end of March to hold the place.

Tuition fees (annual) — main day-school programs

- K–5 (elementary, highest grade offered): USD 23,810 per year. Use of school payment plans (see Billing & Payment Terms) affects timing of payments but not the annual total.

- PreK / LowK: tuition varies by enrollment option (part‑week, full‑week, half‑day vs full‑day) and may be pro‑rated for students who start after the designated start date. The school's published tuition schedule describes those different PreK/LowK enrollment options and pro‑rating rules.

Tuition presented as payment-plan installments (example, K–5 at USD 23,810)

- Full Pay Plan: entire balance due by July 31 (Full Pay amount = USD 23,810).
- 60/40 Plan: 60% due by July 31 (USD 14,286) and remaining 40% due by January 1 (USD 9,524).
- 10‑Month Plan: 10 equal monthly installments starting August 1 (10 × USD 2,381).

(The installment amounts above are simple arithmetic based on the published annual tuition for K–5 and the school's three payment-plan options; they show how the annual charge is split under each available plan.)

Billing schedule and payment terms

- Payment plans available: Full Pay (entire balance by July 31), 60/40 (60% by July 31 and 40% by January 1), and a 10‑month monthly plan (10 equal payments beginning August 1). These plans determine due dates for tuition installments.
- Sibling discount: 10% off the least expensive program for a second child and 15% off the least expensive program for a third child. The discount is applied based on the Full Pay Plan rate for the selected enrollment option.
- PreK start and pro‑rating: PreK students must be age 3 at the start of the school year (with designated start dates) and tuition will be pro‑rated for PreK students who start after the designated start date. "Full day" and "half day" definitions are published for Early Childhood and affect tuition.

Boarding

- Boarding is not offered. The school is an independent preschool and elementary day school (PreK through Grade 5).

Other costs and common additional fees

- Lunches: billed separately; parents should plan to pay separately for student lunches.
- Durable school supplies and personal items: some durable supplies (items students keep and reuse) are not included and are billed or purchased separately by families; most consumable school supplies, many festival costumes, two class parties per year, student books, field trips and many classroom supplies are included in tuition.
- Optional after‑school classes and enrichment (Global Kids / After‑School Enrichment Clubs): these programs carry separate fees; refund and cancellation rules apply (for example, refunds for enrichment clubs are not issued after billing one week prior to the start; Global Kids refund/cancellation policies and non‑refundable reservation fees are published with those program pages).
- School spirit shop / uniform items: the school operates a spirit shop; parents purchase spirit‑wear and other optional apparel items separately. Most day‑to‑day classroom supplies are provided.

Refund information (applicable items)

- Enrollment deposit refund: the USD 500 enrollment deposit is non‑refundable when required with acceptance/enrollment contracts.
- Pro‑rated PreK tuition: PreK tuition may be pro‑rated for students who start after the designated start date (the school publishes its pro‑ration rules).
- After‑school / club refunds: enrichment club billing carries a one‑week prior cutoff; refunds are not issued after that billing point. Global Kids program cancellations made more than seven calendar days before a program date may be eligible for a refund (minus any non‑refundable reservation fee) per the Global Kids policies.

Fee payment options (how families commonly pay)

- The school uses FACTS for tuition‑support (financial aid) applications, and FACTS is widely used by independent schools to manage billing and payment plans. FACTS supports ACH (automatic bank withdrawal) and credit/debit card payments and can administer payment plans, so families should expect to be able to use ACH or credit/debit card payment methods through FACTS where the school uses that service. This is an operational inference based on the school's use of FACTS for financial‑aid processing and FACTS' payment capabilities.

- Practical payment methods you will encounter when completing enrollment and bills typically include: automated bank draft (ACH), credit/debit card (convenience fees may apply through payment processors), and paper check where accepted; the school's billing system and FACTS (if used for tuition billing) will list the exact available methods and any processing fees.

- Expect an application fee (USD 75) and a required non‑refundable enrollment deposit (USD 500) to hold an offered place.
- K–5 annual tuition is USD 23,810; PreK/LowK tuition varies by schedule (part‑week/full‑week, half/full day) and may be pro‑rated. Payment timing is handled by one of three plans (Full Pay by July 31, 60/40 with dates, or a 10‑month plan starting August 1). Sibling discounts are available.
- Lunch, some durable supplies, and optional after‑school or enrichment programs are billed separately; many consumable supplies, books, field trips, and the 5th‑grade capstone trip are included in tuition.
