Lohman, D. F. (2006).  Identifying academically talented minority students. Draft of a monograph prepared for the National Research Center on the Gifted and Talented.  Sample data set.   This excel file shows how to combine scores from CogAT and ITBS to better identify academically gifted students using procedures described in the monograph.. Each student’s standing relative to all other students in the nation, the local school or school district, and any subgroup (such as ELL status) can also be determined. 

Lohman, D. F. (2006).  Understanding and predicting regression effects in the identification of academically gifted children.  Paper presented at AERA, San Francisco.  This talk provided an update and extension of the Lohman & Korb (2006) paper. It contains additional tables and analyses not reported in that document.

Lohman, D. F. (2006).  Identifying academically gifted children in a linguistically and culturally diverse society. Invited presentation at the Eight Biennial Henry B. & Jocelyn Wallace National Research Symposium on Talent Development, University of Iowa, Iowa City.  In addition to general issues in the identification of academically talented minority students, this paper also shows how the NNAT Fall standardization data reported in Naglieri & Ford (2003) were modified to achieve proportional representation of high-scoring White, Black, and Hispanic students.  

Lohman, D. F. (2006). Practical advice on using the Cognitive Abilities test as part of a talent identification system.  The goal of this document is to provide a practical overview of how to make the best use of CogAT as part of an identification system.  Major characteristics of CogAT are also summarized.  Some of the topics that are covered include: understanding scores and score warnings; developing local norms; making test accommodations; estimating Form 6 scores when retesting with Form 5; out-of-level testing to increase reliability; using an excel spreadsheet to combine ability and achievement test scores to identify the most academically talented students in all ethnic groups; and additional resources. (See also 2011 Workshop on local norms, below).

F. & Renzulli, J.  (2007). A simple procedure for combining ability test scores, achievement test scores, and teacher ratings to identify academically talented children In this paper, we show how to convert CogAT scores and achievement test scores to points that can be combined in a simple but principled way.  Then we show how these point totals can be used in conjunction with teacher ratings of creativity, ability, and motivation from the SRBCSS to help identify academically talented children,

Hunsaker (Ed.), Identification: The Theory and Practice of Identifying Students for Gifted and Talented Education Services. (pp. 283-335). Mansfield Center, CT: Creative Learning Press.  This chapter summarizes the uses of both individual and group ability tests in talent identification. It provides the conceptual background for the chapter on decision strategies (see next publication) that will appear in the same book. Together, the two chapters provide the most up-to-date statement of my suggestions on how one might conceptualize the issues and tradeoffs involved in using ability tests as one component of a talent identification process.
