Student-Produced Response (SPR) Rules.
Never lose a point on syntax.
Student-Produced Response (grid-in) questions have no answer choices. Avoid score deductions by understanding character limits, negative sign handling, improper fraction formatting, and repeating decimal truncation.
The 6 Official SPR Formatting Rules
Tested directly on the Bluebook Digital SAT Math testing interface.
Maximum Character Limits
Positive answers allow up to 5 characters (including `/` and `.`). Negative answers allow up to 6 characters (including `-`).
No Mixed Numbers Allowed
Never enter mixed numbers like $3\frac{1}{2}$ (it will be scored as $31/2 = 15.5$). Always convert to improper fraction or decimal.
Fill All Available Spaces
For repeating decimals like $2/3$, you MUST enter all characters that fit: `2/3`, `0.666`, or `0.667`. `0.66` is scored WRONG.
Negative Numbers are Permitted
Unlike the old paper SAT, negative values CAN be entered on the Digital SAT using the leading minus sign `-`.
Multiple Valid Solutions
If a quadratic has solutions $x = 2$ and $x = 5$, enter either 2 OR 5 into the box. Both are graded as correct.
Leading Zeros are Optional
Decimals less than 1 can be entered with or without the leading zero (e.g. `.75` and `0.75` are both completely valid).
