The state's community colleges and universities told a legislative interim committee yesterday about how they are spending a combined $66 million allocated to shrink a gap for middle-skill jobs, The Des Moines Register reported. Lawmakers said expanded and new training programs are "on the right track." One use of the money: The University Northern Iowa bought a 3-D printer for the university's Metal Casting Center that produces molds for metal alloys, which will allow students to gain training while producing casts for Iowa manufacturers. Lawmakers approved the Iowa Skilled Worker and Job Creation Fund last year.
