Background Information

The SDMT manual does not provide Standard Scores, so for assessments in the UK, where Standard

Scores are the most common method for reporting information from educational assessments, a

standard score must be calculated.

WPS, copyright holders and publishers of the SDMT (www.wpspublish.com) recommend that

practitioners use a formula recognised by statisticians in their field. The formula used in this

document is a standard formula widely used by educational statisticians. Practitioners working in

other fields should check the validity of the formula for their own area of work. We have contacted

WPS to inform them of this adaptation of the scoring.

The standardised scores in this document are calculated using means and standard deviations taken

from pages 5 and 6 of the SDMT manual. Because of the limited sample size upon which these historic figures were based, a very few of the

standardised scores look anomalous compared with their neighbouring scores.

Assessors using SDMT in assessments for the Disabled Student's Allowance should refer to the

document 'Updated Guidance on the use of the Symbol Digit Modalities Test' produced by STEC

(the SpLD Test Evalation Committee) for further guidance.

Calculating Standard Scores for the SDMTUsing the tables on pages 5 and 6 of the manual, please refer to the mean and the standard

deviation (in brackets) for the appropriate age group

Subtract the mean score from the student’s raw score

Divide this answer by the standard deviation

Multiply this answer by 15

Add 100 to this answer

Round up or down for the standard score

For example:A student aged 26, with more than 12 years of education, completing the written SDMT, acheving a

Raw Score of 51

1) Subtract the mean score from the student’s raw score

51 - 57.72 = -6.72

2) Divide this answer by the standard deviation

-6.72 ÷ 9.08 = -0.74

3) Multiply this answer by 15

-0.74 x 15 = -11.10

4) Add 100 to this answer

-11.10 + 100 = 88.9

5) Round up or down for the standard score 89

Moira, Fellow of the Royal Statistical Society, Cstat. for their invaluable input to this

project.
