TOWNSEND -- North Middlesex Regional High School Principal Christine Battye is leaving her position to "pursue other career opportunities," according to a statement released on the school district's website Monday.

No details were given about her future plans, and neither Battye or Superintendent Joan Landers returned calls for comment.

"We thank her for leading us through the NEASC accreditation process and her participation in the new high school building process. We wish her happiness and success in her future pursuits," the statement said.

Interviews for an interim principal began on Tuesday, according to the statement. If a qualified candidate for the permanent position is not chosen over the summer, the interim principal will lead the school through the 2014-2015 school year.

The statement also listed several other key staffing changes in the school district.

NMRHS headmaster Christopher Chew will be leaving for a job as principal at Stony Brook Middle School in Westford, beginning July 1.

Pauline Cormier, principal at Varnum Brook Elementary School in Pepperell, will be retiring July 31. A search committee is in the process of interviewing candidates.

VBES assistant principal Eric Magnuson is returning to the classroom to teach fourth grade at Ashby Elementary School. An advertisement for that position is being advertised within the school district.
