A library media center should be staffed by an endorsed library media specialist

A library media center should be staffed by an endorsed library media specialist who is involved not only in identifying materials suitable for school curricula, but also in collaborating with teachers and others in developing curricula. This involvement in the instructional process helps to shape a larger—and, presumably, more appropriate—local collection. Students who score higher on norm-referenced tests tend to come from schools where this instructional role is more prominent.
