Karen Castellano is a data analyst/computational research specialist in the Research & Development division at ETS. She received a B.A. in mathematical sciences from Kean University in 1998 and completed the necessary prerequisites for a master’s of statistics program in 2006 at Rutgers University.

When she first came to ETS, Castellano primarily worked on the College Board’s Admitted Class Evaluation SystemTM, an Internet-based program that helps colleges determine which measures used in admission or placement decisions offer the best prediction of a student’s college performance. Currently, she performs data management tasks for the Programme for International Student Assessment (PISA) and provides support for the national participants. In addition, she is involved with coder reliability for both PISA and the Programme for the International Assessment of Adult Competencies (PIAAC) and is responsible for the maintenance and support of the International Data Explorers for PISA and PIAAC. She also works on the National Assessment of Educational Progress and other special projects as they arise.

Prior to joining ETS in November 2000, Castellano worked in the testing office of Middlesex County College. Additionally, she tutored students in mathematics, statistics, and computer science.
