“We don't have a formal review process for our Board to review our 990; the return is made available to all Board members.”
“To date we have not made our governing documents, conflict of interest policy, or tax forms available publicly, but would do so if the need arose. We are instituting a COI process at our next Board meeting.”
“The $2,259 in manage expenses was for payroll processing fees. $58,902 paid for teachers leading sessions during the school year and over the summer. The remaining $18,346 funds in program paid for lesson planning, teacher workshops, and similar program activity.”
“This adjustment addresses an error for the net assets reported at the end of the previous year. The issue is the manner in which our PPP loan of $14,402 was accounted for. This amount was NOT included in our cash balance at the end of the year. It should have been, so we are adding that amount to our balance sheet to reflect the correct balance as of 6/30/2021.”

| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 0 | We don't have a formal review process for our Board to review our 990; the return is made available to all Board members. |
| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 1 | To date we have not made our governing documents, conflict of interest policy, or tax forms available publicly, but would do so if the need arose. We are instituting a COI process at our next Board meeting. |
| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 2 | The $2,259 in manage expenses was for payroll processing fees. $58,902 paid for teachers leading sessions during the school year and over the summer. The remaining $18,346 funds in program paid for lesson planning, teacher workshops, and similar program activity. |
| IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt | 3 | This adjustment addresses an error for the net assets reported at the end of the previous year. The issue is the manner in which our PPP loan of $14,402 was accounted for. This amount was NOT included in our cash balance at the end of the year. It should have been, so we are adding that amount to our balance sheet to reflect the correct balance as of 6/30/2021. |
