The Wonderlic test is continually being updated with repeated evaluations of questions.
Also, beginning in the 1970s, Wonderlic began to develop other forms of the Wonderlic Personnel, some of which include: Wonderlic Perceptual Ability Tests, Wonderlic Scholastic Level Exam, or the Wonderlic Contemporary Cognitive Ability Test.
Other Wonderlic Tests
The tests are divided into three different types:
cognitive ability, personality, and motivation.
Cognitive Ability
Released in the 1990s, the Wonderlic Personnel Test measures an individual's capability of solving problems and learning. The Wonderlic Personnel Test has two different forms: the Wonderlic Personnel Test--Quicktest (30 questions in 8 minutes) and the Wonderlic Personnel Test (50 questions, 12 minutes). The Wonderlic Personnel Test--Quicktest differs from the Wonderlic Personnel Test in that it is not proctored. The Wonderlic Personnel Test is a much more comprehensive test.
The Wonderlic SLE is the scholastic version of the Wonderlic Personnel Test and is commonly administered to nursing school and medical program applicants.
Personality
The Wonderlic Personality tests measure personal characteristics that are widely accepted as being predictive of a candidate's expected
job performance
Job performance assesses whether a person performs a job well. Job performance, studied academically as part of industrial and organizational psychology, also forms a part of human resources management. Performance is an important criterion for or ...
. Wonderlic claims that using the Wonderlic Personality Test to select individuals whose traits are aligned with the demands of the position, employers can improve employee productivity, employee satisfaction and customer service while reducing recruitment costs and employee turnover.
Added during the 1990s, the Wonderlic Personality Test contains two sections. The Wonderlic Five-Factor Personality Profile and the Wonderlic Seven-Factor Personality Profile. The Wonderlic Five-Factor Personality Profile tests individuals on five primary dimensions of the individual's personality:
extraversion,

, also known as the Five Factor Model.
Motivation
Averaging 10–15 minutes, the 58-item assessment is based on the Holland/RIASEC workplace motivation model. It evaluates a candidate’s interests, which helps predict how motivated they will be by the actual responsibilities of the job. The more motivated they are by those responsibilities, the likelier they will succeed in that position.
Sample questions
Similar to other
standardized tests, the Wonderlic Cognitive Ability Test presents its questions in an open response.
The types of questions that have appeared in the oldest versions of the Wonderlic test include:
analogies

proverb matching, similarities, and word definitions. However, the questions may take different angles depending upon the ‘intelligence’ of the question setters.
Practice questions will include:
* If a piece of rope cost 20 cents per 2 feet, how many feet can you buy for 30 dollars?
* Which of the numbers in this group represents the smallest amount? a) 0.3 b) 0.08 c) 1 d) 0.33
* A high-speed train travels 25 feet in 1/3 second. In 4 seconds, the train will have traveled __?__ feet.
* A clock lost 2 minutes and 36 seconds in 78 days. How many seconds did it lose per day?
Application to industrial-organizational psychology
The Wonderlic test, as a vocational and intelligence test, falls under the field of Industrial and Organizational Psychology. As a personnel test the Wonderlic is used to gauge an applicant's job potential, educational potential, and training potential.
Six forms of this test are made available (A, B, C, D, E, and F) in which Wonderlic suggests that when two of these versions are to be used, the best combinations are A and B or D and F.
[Kazmier, L.J. & Browne C.G.(1959). Comparability of Wonderlic test forms in industrial testing. Journal of Applied Psychology. 43(2):129–132.] However, a study conducted by psychologists Kazmier and Browne (1959) shows that neither of these forms can be regarded as directly equivalent.
While there is no lack of tests that could be used in place of the Wonderlic, such as the IQ or the Mechanical Aptitude Test, it is a quick and simple vocational test for personnel recruitment and selection.
The Wonderlic test has been peer reviewed by the
American Psychological Association

Reliability
In 1956, Weaver and Boneau reported in the ''
Journal of Applied Psychology
The ''Journal of Applied Psychology'' is a monthly, peer-reviewed academic journal published by the American Psychological Association. The journal emphasizes the publication of original investigations that contribute new knowledge and understandin ...
'' that two of the five forms, A and B, that were published at the time were harder than the others which caused scores on those forms to be significantly lower than scores obtained on forms C–F.
Concerning these observed differences, Weaver and Boneau state: "This accords with the history of the development of the test. Forms D, E, and F are made up of items selected from the Otis Higher, while A and B were developed later and include types of items not found in the Otis."
Those findings, seemingly, invalidate the claim that those forms were equivalent or consistent.
E. N. Hay made a similar observation as well. Hay found that form F was significantly easier than Form D. Furthermore, Kazmier found Form B to be the most difficult of the five forms and, thus, recommended that it "not be regarded as directly equivalent to any of the forms."
Kazmier also found Forms D and F to be significantly different from each other and recommended that these forms be regarded as inequivalent.
In a study of the Wonderlic's test-retest reliability, conducted in 1992, Stuart McKelvie "concluded that conscious repetition of specific responses did not seriously inflate the estimate of test-retest reliability."
To put it simply, one's memory of some of the answers does not significantly affect one's score on the Wonderlic.

'', Dodrill reported that the test-retest reliability for the Wonderlic was .94.
According to a 1989 article in ''
Psychological Reports'', the Wonderlic scored a r=.87 on the reliability scale compared along with the Pearson test score of r=.21.
Validity
In an article written in ''
Psychological Reports'', T. Matthews and Kerry Lassiter report that the Wonderlic test "was most strongly associated with overall intellectual functioning," which is what it is purported to measure.
However, Matthews and Lassiter did not find the Wonderlic to be a successful measure of
fluid and crystallized intelligence
The concepts of fluid intelligence (''g''f) and crystallized intelligence (''g''c) were introduced in 1963 by the psychologist Raymond Cattell. According to Cattell's psychometrically-based theory, general intelligence (''g'') is subdivided into ' ...
, and they stated that "the Wonderlic test scores did not clearly show convergent or divergent validity evidence across these two broad domains of cognitive ability."
In academic testing, the Wonderlic test has shown high correlations with aptitude tests such as the General Aptitude Test Battery.

similarly argued that evidence concerning the test's validity was limited. Their research showed "that Wonderlic has no direct relationship to fluid intelligence once its commonality to working memory capacity is accounted for", and that the Wonderlic "was a significant predictor of

capacity for subjects with low fluid intelligence, but failed to discriminate as well among subjects with high fluid intelligence". These findings suggest that the Wonderlic is less informative when administered to higher-than-average ability individuals or groups, meaning there is more measurement error and less practical utility in giving the test to individuals higher in cognitive ability. Partially on this basis, they argued that organizations interested in personnel selection should consider administering measures of established constructs that are grounded in a more theoretical framework, such as fluid intelligence or working memory capacity.

Central tendency of Wonderlic scores
Serving as a quantitative measure for employers, scores are collected by the employers and the applicant's score may be compared to a professional standard, as is the case with security guards or, simply, compared to the scores of other applicants who happen to be applying for the same or similar positions at that time.
Each profession has its own, unique, average; therefore, different professions require different standards.

A 2005 study by McDonald Mirabile found that there is no significant correlation between a quarterback's Wonderlic score and a quarterback's passer rating, and no significant correlation between a quarterback's Wonderlic score and a quarterback's salary.
Similarly, a 2009 study by Brian D. Lyons, Brian J. Hoffman, and John W. Michel found that Wonderlic scores failed to positively and significantly predict future NFL performance, draft position, or the number of games started for any position.
Lyons said that Wonderlic's "limited return on investment" for the NFL is contrary to
