Cayman International School Fees: Is CI$30,700 for Grade 12 Worth It? (2026)

Cayman International School charges CI$30,700 a year for Grade 12 in 2026, roughly US$37,400, and about three times what other well-regarded private schools on the island charge for the same year. So the question every expat family should ask before they sign: is it actually worth it?

This is opinion and commentary. Every fee below is taken from CIS's own published 2026–2027 tuition schedule, the numbers are theirs, not ours.

The full CIS fee ladder

Here's what Cayman International School (CIS) lists for the 2026–2027 school year:

What that actually adds up to

Run one child from Kindergarten through Grade 12 at these rates and you clear north of CI$350,000 in tuition alone, for a single child. Two kids and you're looking at the price of a house on this island, spent on school runs before anyone's bought a uniform.

Is it worth it?

To be fair to CIS: you are paying for something specific. It's an American-curriculum school offering the IB Diploma, it sits in Camana Bay, it's accredited and ISS-governed, and the facilities match the price tag. For families on the international-school circuit or on a firm US university track, that has genuine value.

But "has value" and "worth CI$30,700 a year" are two very different questions, and for a lot of expat families the honest answer to the second one is no. When one line item on your budget costs more than the island's median salary, you are entitled to ask what, precisely, justifies a price roughly three times what other respected private schools charge for the same grade.

The alternatives most expats don't realise they have

Here's what the sticker shock hides: CIS is the most expensive option, not the only one.

Yes, the curriculum differs: CIS is American / IB, while Cayman Prep and St. Ignatius are British (GCSE / A-Level). But if your child is heading for a UK or Commonwealth university, British is arguably the better fit anyway, at a third of the cost. Paying triple for the "international" label only makes sense if the curriculum is genuinely the one your child needs. (For the wider picture, see our guide to the Cayman school system.)

The catch nobody warns you about: the waitlist

There's a reason CIS can charge what it charges, the good, cheaper schools are full. Cayman's most sought-after private schools run waiting lists, especially at the primary level, and new arrivals are routinely shocked at how fast places vanish. The island's population boom has only tightened the squeeze.

So the real trap isn't only the price, it's timing. Land on-island in August with no plan and the priciest school may be the only one with an open seat. You'll pay for the privilege of not having applied a year earlier.

What to actually do

• Apply early, before you move. Get your child on the waitlist at Cayman Prep, St. Ignatius and any other target school 12–24 months out. (Sorting this before you relocate matters as much as finding somewhere to live, worth doing alongside your move to Cayman.)
• Match the curriculum to the destination, not the brochure. UK-bound? British track. US-bound? That's where CIS earns its premium.
• Budget the real number, tuition, deposits, fees, uniforms and the annual increases, multiplied by every child.
• Don't treat the most expensive school as the default. The biggest fee is not automatically the best education for your kid.
