There were two test development committees working on the construction of items for the LOCUS assessments. One of these committees was focused on developing the Beginning/Intermediate versions of the LOCUS Assessments (Levels A and B of the GAISE framework) while the other was focused on developing the Intermediate/Advanced versions of the LOCUS Assessments (Levels B and C of the GAISE framework). This overlap was intentional because statistical education should be viewed as a developmental process. As described in the GAISE framework these levels “are based on development in statistical literacy, not age (Franklin, et al., 2007, p. 13).”

Beginning and Intermediate Test Development Committee

Christine Franklin, University of Georgia (Chair). Chris Franklin is a Senior Lecturer in the Department of Statistics at the University of Georgia in Athens, GA. She is an author of the GAISE framework and has written several articles related to the preparation of teachers to teach statistics at the K-12 level. Franklin also served as a Chief Reader for the AP Statistics Program.

Brad Hartlaub, Kenyon College (Co-Principal Investigator). Dr. Hartlaub is a Professor at Kenyon College and a fellow of the American Statistical Association. Brad specializes in nonparametric statistical analysis. From 2004-2007, Dr. Hartlaub served as the Chief Reader for the AP Statistics Program. Dr. Hartlaub is overseeing the development of all rubrics for the LOCUS assessments based on his experience as Chief Reader for the AP Statistics program.

Gary Kader, (Appalachian State University). Dr. Kader is a Professor of Statistics at Appalachian State University in Boone, NC. Kader was one of the authors of the GAISE framework and has done several studies related to students’ understanding of statistics over the course of his career.

Mary Lindquist, (Columbus State University). Dr. Lindquist is a Professor Emeritus of Mathematics Education at Columbus State University in Columbus, GA. She has extensive test development experience having served on development committees for NAEP, TIMSS, and PISA and is past president of the National Council of Teachers of Mathematics.

Intermediate and Advanced Test Development Committee

Bob delMas, University of Minnesota (Co-Principal Investigator). Dr. delMas is an Associate Professor at the University of Minnesota. delMas has significant experience developing assessment items for an NSF-funded project entitled ARTIST. This project developed online resources for the creation of assessments in undergraduate statistics courses. In addition, Dr. delMas has written extensively on the differences between mathematical and statistical reasoning and served as the editor of the Statistics Education Research Journal.

Roxy Peck, California Polytechnic State University (Chair). Dr. Peck is Professor Emeritus at California Polytechnic State University. Peck is a fellow of the American Statistical Association, has served as the Chief Reader for AP Statistics, and is an author of one of the most widely used textbook series on statistics at the high school level.

Mike Perry, Appalachian State University. Dr. Perry is a Professor Emeritus in the Department of Mathematical Sciences at Appalachian State University in Boone, NC. Perry was one of the authors of the GAISE framework and has been heavily involved in the statistics education community for his entire career.

Josh Tabor, Canyon del Oro High School. Josh Tabor is a high school mathematics teacher at Canyon del Oro High School in Oro Valley, AZ. He has been heavily involved in the AP Statistics program as a member of the test development committee as well as a reader, table leader, and question leader at the AP Statistics exam grading sessions.
