TheKansas City (Mo.) school board still wants an engineering and construction academy, but its president has made it clear that she wants a cheaper version. Members of an industry council had promised to raise $30 million--tripling a proposed school district investment of $10 million--to build a regional showcase school. But Board President Marilyn Simmons says Kansas City should be able to get the engineering and construction program without a multimillion-dollar building project. A plan conceived before recent elections changed the makeup of the board called for renovation of an existing high school facility in a $10 million first phase, followed by construction of a new facility at a cost of $30 million.
