PORTLAND — Superintendent Jim Morse is seeking a new principal to lead East End Community School, one of 10 public elementary schools in the city.

Carol Dayn has resigned from the position, effective at the end of June, Morse said Tuesday.

Morse said Dayn is leaving “for her own reasons” and not because she is being removed from the position.

Morse also said he believes Dayn’s decision to leave wasn’t precipitated by his plan to eliminate three teacher leader positions at the elementary school in the coming year and hire an assistant principal.

The three teachers will return to the classroom full time and will no longer have administrative duties, he said.

Dayn has been East End principal since it opened in 2006. In a letter to East End parents, Dayn said “it is time for someone else to lead East End into the next phase of its development.”

Dayn noted that the school was developing an Expeditionary Learning program similar to King Middle and Casco Bay High schools, which feature real-world, interdisciplinary learning projects.

“Working together with administration and teachers, you will be able to find a leader with the qualities needed to take the school ever closer to our mission and vision,” Dayn said in her letter to parents.

Dayn didn’t respond to a request for an interview.

The East End jobs of principal and assistant principal are among four open principal positions in the district. The others are principal of Deering High School, held by Ken Kunin, who is resigning at the end of June, and assistant principal of King Middle School, held by Kathleen Bouchard, who is retiring.

In addition, Morse plans to work with Peaks and Cliff island residents to determine future oversight of their schools, which have 53 and three students, respectively. The vacant principal’s position they shared has been eliminated in the district’s proposed budget for the coming school year.
