      Each multiple-choice item is worth 1 point.  Each constructed response item is worth 3 points.

 

General Test Format

There will be a total of 65 test questions: 60 multiple choice and 5 constructed response items. 

 

Each content strand will be assessed by 13 items: 12 multiple-choice and 1 constructed response item. Eight of the multiple-choice items will assess content knowledge and 4 will assess scientific inquiry, literacy and numeracy.

 

Test Scoring

The selected response items will be scored electronically as correct or incorrect.  Constructed response items will be hand-scored by trained readers using a 4-point scale (0-3). 

 

Curriculum-Embedded Performance Tasks

SDE will develop a performance task for each of the five strands in the science framework for grades 9-10.  Districts would be encouraged to utilize these tasks when their curricula address the Content Standard related to each task.  The five constructed response items on the written test would assess scientific inquiry, literacy and numeracy in the same contexts as the tasks.  These constructed response items would total 15

points or 20% of the total test.

 

Reporting

A Total Science Score will be reported based on all 75 points.  In addition, the following subscores will be reported:

 

      Energy Transformation                          15 points    20%

      Chemical Structures and Properties                 15 points    20%

      Global Interdependence                         15 points    20 %

      Cell Chemistry and Biotechnology                 15 points    20%

      Genetics, Evolution and Biodiversity              15 points    20%

 

      Content Knowledge                               40 points    53%

      Scientific Inquiry, Literacy and Numeracy      35 points    47%

 

Testing Time

The science test will be divided into two sessions, each 50 minutes in length.
