Scoring Guide and Sample Student Work

Select a score point in the table below to view the sample student response.

Score	Description
4	The student response demonstrates an exemplary understanding of the Algebra concepts involved in creating equations in one variable and using them to solve problems. The student creates exponential equations, based on a formula, and uses them to solve real-world problems.
4
3	The student response demonstrates a good understanding of the Algebra concepts involved in creating equations in one variable and using them to solve problems. Although there is significant evidence that the student was able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result, the response merits 3 points.
2	The student response demonstrates a fair understanding of the Algebra concepts involved in creating equations in one variable and using them to solve problems. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points.
1	The student response demonstrates a minimal understanding of the Algebra concepts involved in creating equations in one variable and using them to solve problems.
0	The student response contains insufficient evidence of an understanding of the Algebra concepts involved in creating equations in one variable and using them to solve problems to merit any points.
