When selecting instruments for a program serving a wide age range, what is reasonable?

• A. Use a one-size-fits-all single-domain instrument
• B. Use tests covering the entire age range to monitor progress over time
• C. Avoid any instruments that can be used mid-program
• D. Only use parent-report measures

Answer: (B)

When a program serves children across a broad age range, you want assessment tools that work across development and can be used repeatedly to track growth. Using tests designed to cover the entire age span lets you measure progress over time within the same framework, so you can see each child’s trajectory and identify when additional support is needed. A single-domain instrument or a tool that isn’t adaptable across ages would likely miss important developmental changes and fail to capture what children are learning across different areas. If an instrument can’t be used mid-program, data gaps would appear and progress monitoring would be unreliable. Relying only on parent-report measures can miss classroom performance and objective behaviors, reducing the accuracy of the picture. So, instruments that span the age range and support ongoing progress monitoring provide consistent, meaningful data to guide instruction.
