Basic Information Name: Peabody Individual Achievement Test- Revised (PIAT-R) Cost: -$461.00 per complete kit including 4 easels, 50 combined test record and written expression, booklists, NU Manual, carry bag. -$630.00 per complete kit with ASSIST-includes ASSIST kit, 4 easels, 50 combined test record and written expression, booklists, NU Manual, carry bag. General Purpose:The purpose of PIAT-R, is to measure the academic achievement of students ages 5 through 22 years old. It is made up of six subtests. The PIAT-R is designed to be employed in an educational or research setting. It offers a multiple-choice format which makes it ideal for assessing low individuals. Administration Time:Approximately50 to 70 minutes Domains Assessed: -General Information -Reading Recognition -Reading Comprehension -Written Expression -Mathematics -Spelling

  3. Description and Example of Assessment Task: (Reading) General Information- -100 open-ended questions -Areas assessed: science, social studies, fine arts, humanities, and recreation -Example questions: “What is the chemical formula of water?” or “Name a color”.

  4. Reading Subtest Reading Recognition- -100 items -Divided into two parts *Part 1- are pre-reading activities and are in multiple choice format *Part 2- the subject reads aloud single represented words

  5. What the subject sees: Part 1 Part 2

  6. Reading Subtest Reading Comprehension- -82 items -Each item requires two plates *The first plate the subject will read silently *The second page the subject will choose the best picture out of a series of four that best represents the meaning of the sentence that they read.

  7. What the subject sees: Plate 1: Plate 2: The pony has a big hat on its head.

  8. Demonstration of the test: PIAT-R Demonstration

  9. Scoring Procedures: Administration: • Untimed but not unlimited time • Administer in order of General Information, Reading Recognition, then Reading Comprehension Scoring: • Determine starting point based on background information • Establish Basal item and Ceiling item before determining the Raw Score • Basal item- lowest item of the highest five consecutive correct responses. • Ceiling item- highest item of the lowest seven consecutive responses containing five errors. • If examinee responds incorrectly to an item after the starting point without establishing the Basal item, the examiner must proceed backward in the items until five consecutive items are answered correctly • Raw Score= Ceiling item minus errors between the Basal item and Ceiling item • Special circumstances regarding reading recognition and reading comprehension

  10. Standardization Sample -The sample contained over 1,000students grades K-12, from four regions of the continental US: West, South, North Central and East. - The sample was selected with the same proportional distribution as the US census data, based on the dimensions of sex, socioeconomic status and race or ethnic group. -Did not include students with special needs or students from Alaska or Hawaii.

  11. Reliability

  12. Validity • Content Validity: • Extensive developmental process for each subtest. • High reliability scores: • Kuder-Richardson • Split-Half • Construct Validity: • Correlated scores with the original PIAT and the Peabody Picture Vocabulary Test-Revised (PPVT-R) • Median correlations between PIAT-R and PPVT-R range from .50 to .72

  13. Considerations -Examiner must be very familiar with procedures and scoring protocol -Basal and ceiling scoring -Reading comprehension portion? -Reliable test with proper execution -Standardization sample over 25 years old -Special needs students not included
