Calculation of the Structure/Writing score

The composite Structure/Writing score is not a combination of the number correct on Structure and a rating on the essay. As stated in the section on adaptive testing, the score on the adaptive Structure section is calculated as a function of the difficulty of the questions given and the examinee’s performance on those questions. The essay rating is weighted to account for approximately 50 percent of the composite score. Because these separate scores (adaptive Structure and essay) are both noninteger values (decimal), their sum
(the composite) is actually on a continuous scale, which is then converted to a scale score (also a decimal value) and then rounded. As a result of this summing, scaling, and rounding, the same integer Structure-only score and an unweighted essay rating can result in slightly different final composite scores. For this reason, it is not possible to provide a table illustrating the exact conversion of Structure and Writing scores to composite scores.

The maximum scale score on Structure is 13. This is the official score examinees would receive if they had a perfect score on Structure and a zero (0) on the essay. An essay rating of 1 would add approximately 3 points to an examinee’s composite Structure/Writing scale score and approximately 10 points to the total scale score. Each successive 0.5 increase in the essay rating adds approximately 1 to 2 points to the composite Structure/Writing scale score and approximately 3 to 7 points to the total scale score. Thus, examinees’ scores on the essay greatly affect not only their Structure/Writing scores but also total scores. Scores are most dramatically affected if examinees do not write an essay at all or if they write an essay that is off topic.

The following example further illustrates how this procedure works. The examinee below viewed these
unofficial scores onscreen:
Sample of unofficial on-screen scores:

Listening 22
Structure/Writing 6 to 25
Reading 22
TOTAL 167 to 230

In this sample, the possible Structure/Writing score of 6 is based on the examinees’ performance on
Structure and an essay rating of 0. This would result in a total score of 167. The score of 25 is based on
the performance on Structure and an essay rating of 6. This would result in a total score of 230. The total
score represents the sum of the three section scores multiplied by 10/3

Given this examinee’s performance on Structure, his or her official scores would be as follows for each
possible essay rating. Note that because of the rounding described above, two examinees with the same
unofficial Structure score and essay rating might receive different official scores once Structure and essay scores are combined.

Essay rating-----Structure/Writing scale score-------Total scale score*
0.0 ----------------------6 -------------------------------167
1.0 ----------------------9 ------------------------------ 177
1.5 ----------------------11 ------------------------------183
2.0 ----------------------13 ------------------------------190
2.5 ----------------------14 ------------------------------193
3.0 ----------------------16 ------------------------------200
3.5 ----------------------18-------------------------------207
4.0 ----------------------19 ------------------------------210
4.5 ----------------------21 ------------------------------217
5.0 ----------------------22 ------------------------------220
5.5 ----------------------24 ------------------------------227
6.0 ----------------------25 ------------------------------230

*Total scores end with 0, 3, or 7 only because of the averaging of the three section scores.
