By using the same scale for the entire unit, the SEPUP assessment system allows teachers to obtain evidence about the students' progress. Without the context or criteria that the SEPUP scoring guide (Table 4-3) provides, a score of “2” on an assessment, could be interpreted as inadequate, even if the scale is 0-4. However, as the scoring guide indicates, in this example, a “2” represents a worthwhile step on the road to earning a score of “4”. In practice, the specific areas that need additional attention are conveyed in the scoring guide, thus a student could receive a “2” as feedback and know what they need to do to improve the piece of work. The scoring guide also can provide summative assessments at any given point.

Using Evidence

Response uses objective reason(s) based on relevant evidence to argue for or against a choice.

Using Evidence to Make Tradeoffs

Response recognizes multiple perspectives of issue and explains each perspective using objective reasons, supported by evidence, in order to make a choice.

3

Provides major objective reasons AND supports each with relevant and accurate evidence.

Uses relevant and accurate evidence to weigh the advantages and disadvantages of multiple option, and makes a choice supported by the evidence.

2

Provides some objective reasons AND some supporting evidence, BUT at least one reason is missing and/or part of the evidence is incomplete.

1
