Which option correctly pairs the tool with what it measures?

• A. Checklists describe the quality of performance; scales capture the presence or absence
• B. Checklists measure frequency; scales measure duration
• C. Checklists capture the presence or absence of a skill; scales capture the quality of performance
• D. Checklists provide numerical ratings; scales produce qualitative notes

Answer: (C)

The main idea here is how the two observation tools differ in what they capture. A checklist is used to mark whether each specific skill or component is present or not in a performance—yes or no for each item. For example, in a task, you’d note if the student uses complete sentences, follows instructions, or stays on task, without judging how well those items are done. A rating scale, on the other hand, is about how well the performance is done, often using a numeric or descriptive range to rate quality, fluency, accuracy, or overall effectiveness. So the pairing that fits best is that checklists capture presence or absence, while scales capture quality of performance. The other options mix up what each tool measures or imply measurements like frequency or duration that aren’t the typical focus of these tools.
