The Denver II is used by healthcare providers to assess child development.
Individuals aged 0 to 6 years.
English
Materials include a test kit containing items packed into a convenient small carrying bag, record forms and a manual. The record form is laid out in such a way that the user can compare an individual child's performance with the standardised group. There is a discussion in the literature of validity studies correlating the DDST with other tests of a similar nature. (The test has now been standardised in Great Britain).
Record Forms for scoring the test are available and a Manual contains full details of standardisation and a series of problems with their corresponding answers arranged in a series of lessons. The DDST was revised and re-standardised in 1990 giving rise to the Denver II, which provides a more relevant, thorough test to screen for developmental delays. The Denver II consists of 125 items (the DDST has 105) divided into four general areas of development. The number of language items has increased (from 21 to 39 on the Denver II) - this was an important objective in revising the test. The new test also includes a scale for rating the child's behavioural characteristics during the test.

For the item reliability study, children were assigned to the same 10 age groups described in the sampling scheme. Over 1,000 cases were tested and the percentage of children in each age group who passed each item was calculated. The test retest reliability over a one week period was 0.95 and the reliability amongst examiners averaged 0.90.
Standardised group consists of over 1000 cases.
20 to 60 minutes depending on the stress tolerance of the child.
