“The accountants engaged in preparing the tax return will sed a draft copy to the business manager and charter school management company for review. The 990 wll be approved by the principal/ceo and finalized for mailing. The complete tax return will be approved by the board for filing.”
“Cabinet level members are required to fill out a form 700 conflict of interest statement policy each year.”
“Management compensation is reviewed and approved by the board at a public meeting and documented in a written employment agreement.”
“All governing documents are maintained on file at the school and are available for review upon request.”
“Santiago operates its charter school under the belief that adolescents deserve a quality curriculum designed specifically for them and that middle school is a time for exploration and discovery for interests. While other middle schools state-wide are cutting their exploratory programs, santiago continues to work so that these invaluable classes remain a part of the curriculum. As a result, each student at santiago has the option of choosing two per year of the following electives: art, vocal music, drama, foreign language, industrial arts, home economics, band, orchestra, speech, reading, and musical theater. All of the elective teachers have received training in the areas of reading and writing, and they incorporate these lessons into their programs in support of santiago's standards-based curriculum.”
“Management believes that the organization has appropriate support for any tax positions taken affecting its annual filing requirements, and as such, does not have any uncertain tax positions that are material to the financial statements. The organization would recognize future accrued interest and penalties related to unrecognized tax benefits and liabilities in income tax expense if such interest and penalties are incurred.”
