TONGANOXIE — The Tonganoxie school district will again be searching for a new superintendent.

Lyn Rantz, the district’s top administrator since 2014, plans to resign at the end of June, she told school board members this week. Rantz provided the Tonganoxie Mirror with a copy of her resignation letter Thursday afternoon.

In the letter, dated Monday, Rantz writes that she’s “learned so much these last two years” as the district’s superintendent.

Rantz joined the district before the start of the 2014-15 school year. She came to Tonganoxie from the Blue Valley school district in Johnson County, where she had served since 2001. She had been principal at Prairie Star Middle School in Leawood for nine years before taking the Tonganoxie position.

Asked what her plans were after June, Rantz told the Mirror she would have “more details of future plans when I am able to share.”

Rantz is the district’s third superintendent in six years. Randy Weseman, who retired as Lawrence schools superintendent in 2009, served as Tonganoxie’s “interim” superintendent from 2011 through 2014. He had planned to serve for a year with the district, but one year turned into three.

Weseman replaced Kyle Hayden, who left Tonganoxie to return to the Lawrence school district. Hayden was an assistant principal at Lawrence High School in the 2004-05 school year. He came to Tonganoxie as assistant superintendent in 2008 and became superintendent in 2009.

Since 2011, more than 160 Kansas superintendents have resigned or retired, according to information provided to the Journal-World by the Kansas School Superintendents’ Association. That means that of the 286 school districts in Kansas, more than half have seen turnover in the superintendent position in the past five years.

Current Lawrence Superintendent Rick Doll, 61, announced in November that he would resign his position at the end of the school year. Doll has accepted a full-time position as associate professor and executive director of the Kansas Educational Leadership Institute at Kansas State University.

Perry-Lecompton Superintendent Denis Yoder recently announced his impending departure from the district. And the De Soto school district is winnowing down its list of candidates to replace Interim Superintendent Ron Wimmer.
