The Bus Puzzle Test for assessing developing language and some performance skills has been standardized on a sample of 425 children living in an inner city area and a rural market town. The age range was 18 months to 4 1/2 years. The study provides levels of achievement in comprehension by age and shows the importance of the 27-33 months period in the development of situational understanding. Assessment of expressive language takes account of the strategies employed by young children to express meaning. The early stages of form perception are examined. Results are provided in graphic and tabular forms and provide a data base for converting an individual child's scores into variation from average.

Vision testing of young children in the age range 18 months to 4 1/2 years.

Four hundred and twenty-five normal children in the age range 18 months to 4 1/2 years have been studied to determine the percentage of children according to age who can be expected to cooperate in a letter-matching vision test using a key card; to see whether the use of plastic letters to replace the key card lowers the age at which a letter-matching test can be achieved, and to show that children in this age range can do a vision test at 20ft (6m). Acceptance of occlusion using a patch occluder was also examined. The study shows that children effectively begin to cooperate in letter-matching vision tests using a key card from 33 months of age. Replacement of the key card with plastic letters lowers the age to 30 months and thereafter there is a gain of some 25% of children up to 39 months. All children were successfully tested at 20ft (6m). The most difficult age for occlusion was in the age group around the second birthday.

Developmental assessment: 18 months to 4 1/2 years. The miniature toys test.

A modified version of the miniature toys test, originally designed by Sheridan (1975), has been standardized on a sample of 425 children in the age range 18 months to 4 1/2 years. The distinctive features are the assessment of symbolic play and the understanding of prepositions when used in verbal instructions. The acquisition of expressive verbal labels for miniature household objects and transport, and comprehension of questions relating to them have been explored. Responses in some of these areas are not always clear-cut or are ambiguous. The test will be more suited to the needs of the developmental paediatrician for assessment of children with developmental delay, than for doctors of primary care and health visitors in screening apparently healthy children.

Developmental assessment: 18 months to 4 1/2 years. Performance tests.

Performance tests of young children in the age range 18 months to 4 1/2 years have been studied in a sample of 425 children living in an inner city area and a rural market town. Our results show that there is a minimum number of cubes built into a tower related to age which may indicate developmental delay. There is a developmental sequence of pencil grasp, and useful development scales in copying cube models, drawing geometric shapes, and the draw-a-man test. Girls are significantly ahead of boys in drawing skills.
