Contents: • Purposes • Structure • Nature • Use

Test parameters

1. Purpose

2. Spec structure: • General Description (GD) • Prompt Attribute (PA) • Response Attribute (RA) • Sample Item (SI)

3. Nature: Essence

3. Nature: Reiterative process

3. Nature: Spec bank

3. Nature: mix of ingredients • Test essence • Proficiency (psychological, cultural skills) • Criterion-referenced • Validity and consistency ………………………………. • Takes time (reiterative process) • Context dependent • Mandated • Takes team effort

4. Use: calibration • Internal • External

4. Internal calibration • Prompt Attribute (PA): general enough • Response Attribute (RA): observable

4. External calibration • Context & Mandate • Knowledge / skills selection • Spec writing • Item writing • Assemble test • Finalize, operationalize, measure

Spec structure: • General Description (GD) • Prompt Attribute (PA) • Response Attribute (RA) • Sample Item (SI)

Today’s tasks • Matching line numbers: spec features with their reflections in the SI • Identification of deviations from a spec in its SI • Generating (writing) a SI from a spec

Task 1 Match the following line numbers of the spec with lines of its Sample Item in which spec characteristics are reflected. Make collective decisions.

Task 1: the answers

Task 2 Identify deviations from the spec in its Sample Item. In your worksheet, write down the SI line number in which a deviations is identified and explain it. Make group decisions.

Task 2: the answers

Task 3 Generate (write) a Sample Item from the spec. Discuss your decisions with your partners.
