“This section has been revised to clarify the Board shall elect a Chair and Vice Chair of the Board who shall also be elected as the President and Vice President of the Corporation. The Board Chair shall be elected for a three-year term and may be elected for a consecutive three year term. No person shall serve more than two consecutive terms as Chair without a two thirds vote of the Board. The Vice Chair shall be elected annually and that person may be elected for more than one term. The number of Trustees has been changed from nine to twenty-one to nine to twenty-five. The Headmaster and PA President are members of the Board by virtue of their ex officio position and both are voting members of the Board. Also, clarifies that Trustees emeriti are not voting members of the Board. Trustees may serve up to three 3 year terms for a total of nine years. To be elected beyond the third term a Trustee must first have been off the Board for at least one year or with a two thirds votes of the then entire Board. In addition to the Conflict of Interest Policy a Confidentiality Policy for all trustees has also been added. Officers of the Corporation - this section is now legally correct, previously it was named Officers of the Board. The Corporation has a President, Vice President, Treasurer and Secretary. The President of the corporation is the Chair of the Board and The Vice President is the Vice Chair of the Board. The Treasurer and Secretary are officers of the Corporation, not the Board. The revised bylaws allow a non-trustee to serve on Board committees and be a voting member of that committee.”
“The School has a finance/audit committee that reviews the tax return before it is filed.”
“The Board of Trustees has a written Conflict of Interest policy and a copy is given to each Trustee once a year to be read, signed and collected by the Board secretary and filed for record.”
“The national, state and regional independent school organizations, to which this school is a member, collect statistical data every year including salary and benefit information of key employees. The results are used as comparability data in determining fair salaries. a. The Headmaster's salary and expense account are determined by the Executive Committee of the Board of Trustees. All other benefits are the same as all other employees of the school. b. The salary for the Business Manager and other key employees is determined using the same comparability data, with annual increases determined as a percentage by the full Board of Trustees.”
“The School makes these documents available to the public upon request.”
“The primary use of the funds is to provide income for the School. Within these funds donors have specified uses for scholarships, technology, and learning center.”

“Special events ($81,230), cost of goods sold ($98,817) and bad debt ($39,700).”
