After two years as Wiscasset High School’s athletic director and assistant principal, Sarah Ricker, said she was surprised to no longer be with the school department.

In another development, Ricker said she has been appointed head of school for a proposed Sheepscot Bay Charter School that would seek to be housed at Wiscasset Primary School.

The proposed grades nine through 12 school is not trying to compete with the newly renamed Wiscasset Middle High School, Ricker said in a telephone interview July 23. Wiscasset has a number of towns around it that send students to area schools; having a charter school in town may attract more students to Wiscasset’s public schools, she said.

In discussing the end of her service at the former high school, Ricker, of Pittston, said she wasn’t fired, but that it was felt she wasn’t a good fit for the school department.

Each of the two years she worked there, she had a one-year probationary contract that is typical of new hires, she said. At the end of April, then-interim Superintendent of Schools Lyford Beverage handed her a letter from him stating that he was not recommending her for the position, she said.

The letter was an absolute surprise, she said, adding that she then had school tennis, softball and track activities to go to that same day.

She is not currently seeking her job back.

“At this point, no,” she said.

But she would go back to work if the department wanted her; she enjoyed the students and was trying to move the athletic program forward, she said.

Her last day with the school department was June 30, she said.

Emails to Wiscasset Middle High School Principal Cheri Towle and Superintendent of Schools Heather Wilmot were not immediately returned.

As for seeking to have the primary school as the site of the charter school, the building is bigger than what the new school would need, so the charter school would probably seek some kind of a shared arrangement, such as leasing it from the town or whoever the town sells the property to, or possibly a shared ownership with another party, she said.

Organizers of the proposed Sheepscot Bay Charter School plan to make a presentation at the Wiscasset School Committee’s July 30 meeting. The meeting starts at 6 p.m. in the Wiscasset Middle High School library.

Organizers sought the presentation in hopes that the charter school will have a relationship with the school committee, Ricker said. What that relationship would involve would still need to be explored, she said.

In a letter the school department provided at the Wiscasset Newspaper’s request, Ricker, on behalf of the Sheepscot Bay Charter School’s inception committee, tells the Maine Charter School Commission that the school’s mission is to “prepare a diverse group of students for the future by equipping individuals with skills, knowledge and attitudes to become self-motivated, resilient learners ... We aspire to make learning challenging, inspiring and rewarding.”

The school would focus on hands-on, exploratory learning and would involve entrepreneurship and internships in the community, Ricker said.

The Morris Farm, next door to the former primary school, is helping by serving as the fiscal agent during the application process, Ricker said in the interview and the letter to the commission. The school should find out in November if it has been approved as a charter school, she said. The plan would be to open the school in fall 2016.

Organizers plan to meet with Wiscasset selectmen about the school’s interest in the primary school building, but wanted to meet with the school committee first, she said.

Selectmen decided July 21 to put the primary school property on the market.
