“Form 990 is reviewed and approved by the head of school and the audit committee. Prior to filing, the final draft of the form 990 with schedule b redacted is made available to the board of trustees for their review.”
“Trustees are required annually to sign conflict of interest statements and disclose any known or potential conflicts of interest in these statements and as they arise throughout the year.”
“Each year, the compensation committee of the board conducts a benchmark analysis to evaluate all components of the head of school's compensation package, including base salary, school-wide benefits, deferred compensation, other compensation, housing, excess remission, and vehicle usage. The benchmark group includes tower hill school and 38 other similarly-situated schools in the us. The compensation committee documents the meeting, including a full list of those present and their independence, and the process used to conduct their review. The committee then presents their recommendation to the full board for review.”
“Governing documents, financial statements and form 990 are held with the school and may be made available upon request.”
“The audit committee is responsible for the oversight of the audit and selection of the independent accountant. This process remains unchanged from the prior year.”

The school recognizes accrued interest and penalties associated with uncertain tax positions, if any. There were no income tax related interest and penalties recorded for either of the years ended june 30, 2022 or 2021.”
