Shrock and Coscarelli

Testing Human Competence


For the past 26 years, Sharon Shrock and Bill Coscarelli–as Shrock & Coscarelli–have provided testing, certification, and evaluation solutions for a number of global organizations.

Our book Criterion-Referenced Test Development: Technical and Legal Guidelines for Corporate Training and Certification, is a standard corporate reference. It is also the basis for our CRTD workshop and has won two professional society awards as the year’s outstanding publication.

We provide workshops and consulting on nearly all issues related to Level 2 Assessment or Certification.

Our work has taken us to five countries with over 50 clients.  In our most unique partnership we established a formal relationship between Southern Illinois University and Hewlett-Packard to complete a global needs assessment on certification and to found the H-P Worldwide Test Center.
