Non-Specific Patient Population

  • The DAT was first published in 1947 and has multiple forms and levels.
  • The DAT contains eight scales:
    1) Verbal Reasoning (VR)
    2) Numerical Ability(NA)
    3) Abstract Reasoning (AR)
    4) Perceptual (Clerical) Speed and Accuracy (PSA)
    5) Mechanical Reasoning (MR)
    6) Space Relations (SR)
    7) Spelling (SP)
    8) Language Usage (LU)
  • Nine scores are provided, one for each scale and a composite score from VR and NR called the Scholastic Aptitude (SA) score.
  • All the tests except PSA are multiple-choice. In MR, problems are presented using drawings. Users may choose to score the tests by hand, by scanner, or to have them scored by The Psychological Corporation.
  • Maximum and minimum standard scores not established in research but reported in DAT manual.
  • The DAT is linked to the Career Interest Inventory to assist with vocational counseling and planning.

Number of Items

  • Paper and pencil for Standard Administration
  • Computer, keyboard, and mouse for Computerized Administration

Considerations

  • The DAT can be effective in a vocational assessment, determining what specialized areas one might focus in on for employment. (Layton & Swanson, 1958)

  • The DAT loses its ability to differentiate between individuals in higher education and advanced students.

  • The DAT is used in numerous international studies and has yielded results similar to the American version of the test.

  • Based upon the research articles, the DAT is a reliable and valid testing measure, however the time period of each article should be taken into consideration for future application of the DAT.

Standard Error of Measurement (SEM)

First Year Secondary School Students(Evers & Mur, 2000)

All SEM values were calculated used Standard Deviations & ICC from the above citation:

  • SP:SEM= +/- (4.57 - 4.13)

    (Video) Differential Aptitude Test (DAT)

  • LU:SEM= +/- (3.53 - 3.19)

  • VR:SEM= +/- (3.53 - 3.19)

  • AR:SEM= +/- (3.34- 2.56)

  • SR:SEM= +/- (4.08 - 3.13)

  • MR:SEM= +/- (3.79- 2.91)

  • NA:SEM= +/- (2.72- 2.09)

  • PSA:SEM= +/- (3.09- 2.37)

Normative Data

The 5th edition of the DAT was normed on a sample of 84,000 students in grades 7 to 12.

First Year Secondary School Students (Evers & Mur, 2000)

  • SP: Mean= 55.6 (8.8)

  • LU: Mean= 25.3 (6.8)

  • VR: Mean= 16.1 (6.8)

  • AR: Mean= 31.5 (8.1)

  • SR: Mean= 29.1 (9.9)

  • MR: Mean= 36.7 (9.2)

  • NA: Mean= 16.8 (6.6)

  • PSA: Mean= 28.2 (7.5)

Boys& Girls in UK Secondary Schools (Lynn, 1992)

Means are available for males and females for all DAT subsets.

13-14 year olds:

  • Males: Mean= 13.6 to 54.8

  • Female: Mean= 12.0 to 56.3

14-15 year olds:

  • Male: Mean= 15.8-57.9

  • Female: Mean= 14.4 to 62

15-16 year olds:

  • Male: Mean= 18.1 to 63.1
  • Female: Mean= 16.3 to 67.9

16-17 year olds:

  • Male: Mean= 26.9 to 76.1
  • Female: Mean= 22.9 to 78.8

17-18 year olds:

  • Male: Mean= 30.2 to 81.4
  • Female: Mean= 25.8 to 86.0

The test reports results in percentile rankings based on age and gender and Stanines with a mean of 5 and SD of 2

Test/Retest Reliability

Unknown Population (French & Beaumont, 1991)

  • Language Usage Test: Excellent(ICC = 0.89)

    (Video) DIFFERENTIAL APTITUDE TEST

  • Spelling Test: Excellent(ICC = 0.91)

Internal Consistency

Secondary school minority group students (Evers et al., 2000)

  • Excellentfor AR, SR, MR, NA, PSA, subscales: Cronbach’s alphas= 0.83 - 0.90

  • Adequate for SP, LU, VR subscales:Cronbach’s alphas= 0.73 - 0.78

(Wang, 1993)

  • Excellent internal consistency coefficients computed with the K-R 20 formula (For all DAT subsets r varied from 0.82-0.95)

Kuwait Petroleum Corporation (KPC) refinery operator trainees(Alkhadher, et al. 1998)

  • Adequate predictive validity for NA test when correlated to first year mathematics scores at the University of Minnesota Institute of Technology (r= 0.45)

  • Poor predictive validity for the AR test when correlated with overall evaluation and with all training courses (For all DAT subsets r= 0.19-0.21)

  • Poor to Adequatepredictive validity for the MR test when correlated with overall evaluation (For all DAT subsets r= 0.26-.031)

Concurrent Validity:

Eleventhgrade students (Wolking, 1955)

  • Excellent concurrent validity on VR test when correlated to verbal scores on Test of Primary Mental Abilities (PMA) (r= 0.74)

  • Excellent concurrent validity on NA test when correlated to numerical scores on PMA (r= 0.63)

Construct Validity

Convergent Validity:

Iowa (U.S.A)high school students (Doppelt & Wesman, 1952)

  • Excellent convergent validity for VR when correlated to Tests of Educational Development (TED) General Vocabulary scores (For all DAT subsets r= 0.69-0.88)

Content Validity

Not statistically assessed, however after thorough review and revising the test content was deemed to be appropriate considering the purposes of the DAT (Wang, 1993)

Face Validity

Not statistically assessed, but the items for each subtest appear to represent the corresponding aptitude being measured (Gray, 1965)
