The board will decide at its Jan. 14 meeting whether to call a special election to fill the post for the remainder of the term or to appoint someone instead.
Although the Jan. 14 meeting will be her last official one, "I have committed to smoothing the transition until a new board member takes office," Ms. Rich said in an announcement issued by the school district on Jan. 6.
Although her children had already left the district's schools, which serve students from kindergarten through eighth grade, Ms. Rich ran for re-election in 2010 to see to the end campus reconstruction projects, she said at the time. The last of those projects, the transformation of the Hillview Middle School campus, was completed in September 2012.
Now, she said in the announcement, "the district has beautiful new facilities; is financially healthy; and has a leadership team of exceptional strength and dedication."
