SBAC Math Rubrics for Scoring

All SBAC problems are worth 1, 2, 3 or 4 points.  For performance tasks, the problem may be broken into parts, with each being worth 1-4 points.  Below is a generic 4-point rubric provided by Smarter Balanced.  You can view the generic rubrics for 3, 2, and 1 point problems here.


Many of the released items from Smarter Balanced include a rubric, modeled after the generic rubric, which provides additional details about how the problem will be scored.  Below is Sample Item 43028, called "ebooks", from this website.  The rubric for "ebooks" is below the problem.


Rubric for "ebooks".


The performance task problems are longer, and so the scoring is broken down into different parts for the problem.  Below is the introduction to the performance task called "Thermometer Crickets".  In this task, students are asked to find a line of best fit for a set of data, and compare this model to a classic model for chirps-per-minute to temperature called Dolbear's Law.  The rubric for "Thermometer Crickets" is posted below the problem.





The rubrics for the SBAC Practice Test can be found here.
