What Greater Portland Christian School does
Mission
Greater Portland Christian School provides a christian education, which compliments the home and the church, brings a biblical perspective to each subject, and helps parents prepare their children for a god-glorifying life.
As stated on its FY2025 Form 990.
Program
The organization offers a full program of study, focusing on the classics and core courses, whose mastery is expected of an educated person. Both college preparatory and general courses are offered with accelerated classes offered in language and mathematics through calculus. Spanish is offered as a foreign language. The primary purpose of the pre-school program is to inspire the joy of learning in children, and, to start them on a life long journey of learning.

The program described on its FY2024 Form 990. Program spending in total: $849,697.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $529k to $721k (+36%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 12%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
