The JCQ is provided with research documentation to most users free of charge, but commercial and very large research projects pay a usage fee to support comparative reliability analysis and instrument development on a nonprofit basis through the JCQ Center, University of Massachusetts Lowell.
Users should request the instrument from the JCQ Center, located at the Øresund Synergy ApS in Denmark, by telephone +45 40461000 or by sending an e-mail to jcqcenter@oresundsynergy.com.
