“The school does not have any committees who have the authority to act on behalf of the board of trustees.”
“The board of trustees reviews a copy of the form 990 prepared by the school's independent accountants. Any resulting comments are incorporated into the form 990 by the independent accountants and a final copy of the form 990 is provided to the board of trustees prior to its filing with the irs.”
“Each interested person must sign an annual statement which acknowledges that: they have received a copy of the conflict of interest policy; they understand it; and they will comply with the policy. Additionally they must state whether or not they have a potential conflict of interest, and list any such potential conflicts of interest. Potential conflicts of interest that arise after the annual statement has been submitted will be disclosed immediately.”
“The board of trustees determines the salary of the head of school. A sub-committee of the finance committee and the board of trustees compiles comparative data of other schools director's salaries to support this process.”
“The organization's audited financial statements are available on certain public and regulatory agency websites and upon request. The organization's governing documents and its conflict of interest policy are available upon request.”
“Financial aid reported as an expense on form 990. Direct fundraising expenses netted with revenue”
“Financial aid treated as a reduction of revenue on the financial statements direct fundraising expenses netted with revenue”
“At june 30, 2025, the school's endowment assets totaled $555,807. Of this, $30,000 is donor restricted to be maintained in perpetuity with investment earnings (interest & dividend income and unrealized gains/losses) on those assets totaling $91,904 at june 30, 2025 which may be appropriated for the enrichment and/or development of the school's mathematics program. Another $338,816 is donor restricted to be maintained in perpetuity in conjunction with the board-designated endowment which was established to provide investment returns for use in general operating support, program support for curriculum enrichment and professional development, to provide flexibility to respond to future opportunities in the areas of program expansion or capital purchases, and to provide emergency reserve funds. The distribution rule as set by the board of trustees is 3% of a 5 year rolling average asset value, and is contingent upon reaching a minimum total corpus of $2,000,000. Investment earnings (interest & dividend income and unrealized gains/losses) on those donor-restricted assets totaling $95,087 at june 30, 2025.”
