What Lakeside School does
Mission
The mission of Lakeside School is to develop in intellectually capable young people the creative minds, healthy bodies, and ethical spirits needed to contribute wisdom, compassion, and leadership to a global society. We provide a rigorous, dynamic academic program through which effective educators lead students to take responsibility for learning. We are committed to sustaining a school in which individuals representing diverse cultures and experiences instruct one another in the meaning and value of community and in the joy and importance of lifelong learning.
As stated on its FY2025 Form 990.
Programs
Lakeside School continues its focus on the core elements of its mission: academic excellence, diversity, and global education, to provide a world class education for the 21st century. In addition to its comprehensive school-year program, the school offers a rich array of summer academic courses and stem and athletic camps as well as the lakeside experiential educational program (leep), which serves rising 6th and 9th graders in the seattle public schools by providing greater access to lakeside's campus and opportunities.

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. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $325M to $427M (+31%).
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.
52% of LAKESIDE SCHOOL’s revenue is contributions — more reliant on donations than three-quarters of its peers (14% for the typical peer).

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 24 funders to 40 funders, grant income rose $687k → $17M.
18 of 69 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 24% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
LAKESIDE SCHOOL leans on a few funders — its largest provides 66% of grant income and the top three 76%; half comes from just 1 funder.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.
How long its funders stay
59% of LAKESIDE SCHOOL's funders are still giving 3 years after their first grant; 87% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
91% of LAKESIDE SCHOOL's grant income comes from Washington funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $9.3M arriving through sponsors registered in 12 states 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.
