institutional caller ID improved callbacks and participation versus an 800 number; optimized call scheduling improved participation; an optimized number of call attempts by disposition type reduced costs and improved participation; and having call centers in different time zones led to improved contact and call scheduling.

NATIONAL CENTER FOR SCIENCE AND ENGINEERING STATISTICS

Work by the National Center for Science and Engineering Statistics (NCSES) centers on research to minimize nonresponse, handle nonresponse statistically, and evaluate nonresponse bias. Future research, according to Steven Cohen of the NCSES at the panel’s workshop, will focus on responsive designs, increased use of paradata, and nonresponse bias analysis on the National Survey of College Graduates by making comparisons to the American Community survey.
