Developmental age and delay in assessment reports: writing them so parents understand

A mother reads that her four-year-old's developmental age in communication is 24 months. The line is accurate, but on its own it may frighten her more than it helps. How the number is presented decides what parents do with it.

Developmental age and delay in assessment reports: writing them so parents understand

What developmental age means

Developmental age estimates the level at which a child performs in a given area, compared with what is expected in typical development. Delay is the gap between that level and the child's chronological age, sometimes shown as a percentage.

The number differs from one area to another. The same child may be close to age level in motor skills and behind in communication, which is why it is shown area by area.

Make the number part of a story

  • Start with what the child can do today, then the gap.
  • Link each gap to a goal in the plan, so parents see what happens after the report.
  • Use a simple chart where possible. A chart shows the comparison between areas faster than a table.

Compare the report with the last one

An assessment shows its real value at the second and third round. With results side by side, parents and the team see progress in each area instead of a single number from one moment.

How this works in Enable 360

Reports come out of the system in the format therapists know: a cover page, a VB-MAPP page across its three levels, and developmental age and delay. Up to four assessments of the same type can be combined into a report, a plan or a cumulative report, so progress over time is visible.

Frequently asked questions

Is developmental age a diagnosis?

No. It describes performance in certain areas at the time of the assessment and is read alongside the rest of the report.

Why does developmental age differ between areas?

Development does not move at the same pace in every skill, so each area is shown separately.

How many assessments can one Enable 360 report combine?

Up to four assessments of the same type, in a report, a plan or a cumulative report.
