## Proficiency Scale

 Score Description Sample Activity Advanced In addition to Score 3.0, the student demonstrates in-depth inferences and applications regarding more complex material that go beyond end of instruction expectations. The student will be able to use a variety of techniques to determine the area of a shape. 3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success. Proficient “The Standard.” The student demonstrates no major errors or omissions regarding any of the information and processes that were end of instruction expectations. The student will be able to determine the perimeter and area of various shapes on the coordinate grid. Determine the perimeter of the following polygon. Perimeter = ______ units 2.5 The student demonstrates no major errors or omissions regarding the simpler details and processes (Score 2.0 content) and partial knowledge of the more complex ideas and processes (Score 3.0 content). Progressing The student demonstrates no major errors or omissions regarding the simpler details and processes but exhibits major errors or omissions regarding the more complex ideas and processes (Score 3.0 content). The student can recognize and recall terminology to answer questions. The student can compute the perimeter or area of a figure on a coordinate plane without needing to use the distance formula 1.5 The student demonstrates partial knowledge of the simpler details and processes (Score 2.0 content) but exhibits major errors or omissions regarding the more complex ideas and procedures (Score 3.0 content).
