Q&A with Drs Naglieri, BRULLES and Lansdowne

Learn More about the Naglieri General Ability Tests

The Naglieri General Ability Tests by Jack A. Naglieri, PhD, Dina M. Brulles, PhD and Kimberly Lansdowne, PhD were explicitly developed to address the need for equitable assessment of gifted students from diverse cultural, linguistic, and socioeconomic backgrounds so they can receive educational opportunities appropriate for their ability. Watch Part One of our Q&A with the authors of the Naglieri General Ability Tests as they discuss the test and its components and the need for equitable assessment in the field of gifted and talented. 

Equitable Assessment

What did past research on the Naglieri Nonverbal Ability Test reveal?


The Naglieri Nonverbal Ability Test, now in its third edition (NNAT3) , has been shown to be a tool that can provide equity across race, ethnicity, and gender. In addition, several research papers have been published showing that males and females get remarkably similar scores on the NNAT. In addition, another publication written by Jack A. Naglieri and Donna Ford have found that similar proportions of Black, White and Hispanic students earned scores high enough to be considered for gifted educational programs, which could address the problem of under-representation of Blacks and Hispanics. Although the NNAT is the third most widely used tool for identification of gifted students, professionals in the field have also asked for verbal and quantitative tests which is why the Naglieri General Ability Tests were created. 


How were these tests developed?


Authors Jack A. Naglieri, PhD, Dina M. Brulles, PhD and Kimberly Lansdowne, PhD developed tests that they thought would be equitable if they did three things. First, devise a way to show, rather than use verbal directions, students what they need to do to complete the test. Second, present test questions that could be solved in any language the student desires. Third, eliminate the need for students to answer the questions verbally by using the multiple-choice format. 


Is there any evidence that your goal of equitable assessment was achieved?


The answer is yes. Based on a research paper currently under review for publication entitled, “Achieving Equity: Race, Ethnic, Gender, and Parental Education Level Differences on Verbal, Nonverbal, and Quantitative Naglieri General Ability Tests,” by Selvamenan, Paolozza, Solomon, Naglieri, and Schmidt (2020). In this publication reported that there was little to no differences across race, ethnicity, gender, and parental education on the Verbal (N = 2,482), Nonverbal (N = 3,488) and Quantitative (N = 2,440) tests for public and private school students in K-12. The results support our expectation that the confounding impact of language and knowledge, particularly in the directions, test content, and response format, can be minimized to achieve an equitable way of assessing diverse populations of students for gifted educational programs.

Test Questions and Format

What are some of the innovative aspects of these three tests?


The most innovative aspect of the Naglieri General Ability Tests, is the way the authors have structured the interaction between the student and the test. 

For example, the authors asked the question, 

“How can we inform the student about the demands of the test without using oral or written directions?” 

The answer was to show the student what to do using an animated video of a ‘student’ in front of a computer. As the video plays, the avatar moves the mouse and curser moves accordingly. The video illustrates how to respond to the item and then how to advance to the next item. This format is used when the test is administered online and a four-frame pictorial version of the video is used when the test is administered on paper. 

Making the test questions for all three tests accessible regardless of what language the student speaks was accomplished by using pictures and diagrams to measure general ability within verbal, nonverbal and quantitative contexts. 

To eliminate the need for the student to verbally explain the answers (as is typically done on traditional measures of IQ), the student selects a picture that indicates their response. These procedures allow students to solve the test questions regardless of what language(s) they know. 


What was the test modeled after?


This test was modeled after the neuropsychological work of A. R. Luria. The nonverbal test (Naglieri-NV; Naglieri, 2021) is like those published in the past, but with new kinds of items. The Naglieri-NV measures general ability using questions which require a student to carefully examine shapes presented in a matrix where sequences, spatial orientations, and other distinguishing characteristics must be analyzed to determine the answer. The Quantitative test which Jack A. Naglieri, PhD and Kimberly Lansdowne , PhD created (Naglieri-Q; Naglieri & Lansdowne, 2021) measures general ability using questions which require a student to closely examine the relationships among the numbers and/or symbols using basic math concepts. All three of these tests measure what is referred to as general ability, which is sometimes designated by the letter g.


How is this test administered? 


The Naglieri General Ability Tests are group or individually administered using online (summer 2021) or paper (estimated publication date 2022) formats for students aged 4 to 18 years. Initial release will be based on local norms to identify students for gifted educational services using the Verbal, Nonverbal, & Quantitative versions of the Naglieri General Ability Tests (Naglieri, Brulles, & Lansdowne, 2021).

Distinguishing between two Tests

Naglieri General Ability Tests: Nonverbal

“How are the Naglieri General Ability Tests: Verbal (Naglieri & Brulles, 2022), Nonverbal (Naglieri, 2022) and Quantitative (Naglieri & Lansdowne, 2022) different from the Naglieri Nonverbal Ability Test, also known as the NNAT?

The  Naglieri Nonverbal Ability Test (NNAT) measures general ability using only nonverbal test questions. The Naglieri General Ability Tests measure general ability using verbal, quantitative and nonverbal test questions. Conceptually the two are the same; the questions are made using shapes like circles and squares arranged in columns and rows as shown below. The questions measure general ability very efficiently because the child must understand the relationships among the shapes and very little knowledge is needed to arrive at the answer.

Why did the authors add verbal and quantitative tests added to the nonverbal test?

Verbal and quantitative tests were added so a more diverse approach to measuring general ability could be achieved. The three separate tests also allow the  user to  select any combination desired when testing a student.

Naglieri General Ability Tests: Verbal

How does the Naglieri General Ability Tests; Verbal test compare to the Naglieri General Ability Tests Nonverbal version?

Like the Naglieri Nonverbal the Naglieri Verbal test questions require the child to understand the relationships among six pictures when five of the pictures represent a verbal concept and one does not. In this example, the concept is “empty.” In this example, pictures are used so that the student can solve the problem using any language and while very little knowledge is needed to arrive at the answer.

Naglieri General Ability Tests; Quantitative

How does the Naglieri General Ability Tests; i Quantitative test compare to the Nonverbal version?

Like the Naglieri Nonverbal and Verbal, the Naglieri Quantitative test questions require the child to understand the relationships among things, in this case numbers. All the questions require simple math and can be solved regardless of the language(s) used by the child and very little knowledge is needed to arrive at the answer. 

Do these tests measure different kinds of ability?

The Naglieri General Ability Tests: Verbal, Nonverbal and Quantitative do not measure different kinds of intelligence, they all measure the concept of general ability. When the three tests are used as a group, a broad measure of general ability is obtained.
