Measures the development of spatial concepts in visually-impaired children.
Everett Hill, Ed. D.

• Age Range: 6-10 years

The Hill Performance Test permits teachers and mobility specialists to assess basic spatial concepts such as front, back, left, right, etc., in visually-impaired children.

The same concepts are tested through performance tasks, in different ways. Children are asked to demonstrate:

• Positional relationships of various body parts
• Positional concepts by moving various body parts, in relation to one another
• Positional concepts by moving the body in relationship to objects
• Object-to-object relationships

The test may be used as a criterion-referenced instrument, to identify individual strengths and weaknesses in the area of positional spatial concepts, or as a norm-referenced test.

Internal consistency is high (.97). Normative data is provided in a number of ways: Percent passing each item by age; Percentiles according to age; Percentage of children passing each item, by reading modes (braille, large or regular print) Item difficulty, discrimination index and proportion of correct answers were collected from a national sample of 273 visually-impaired children.

The Hill Performance Test Kit includes the Manual and a package of Record Forms.
