Now you can have a reliable and valid measure of intelligence in young children that is more age appropriate and user friendly. Long a standard in early childhood ability assessment, the Wechsler Preschool and Primary Scale of Intelligence™ has been revised to reflect both feedback from users of the WPPSI-R and contemporary advances in the fields of cognitive development, intelligence theory and cognitive neuropsychology. 

New Features and Extensive Improvements:

• De-emphasis on performance under time constraints 
• Revisions to WPPSI-R subtests as well as the introduction of new subtests.

Age Appropriate:

• Subtests are designed according to the nature of cognitive development.

Outstanding Psychometric Properties:

• Lower floors and improved ceilings 
• The age range has been lowered to 2:6 and the scale has been divided into two age groups: 2:6-3:11 and 4:0-7:3 
• Excellent reliability and validity data.

More User-Friendly: 

• Examiner instructions and scoring procedures have been simplified to ease administration 
• The page layout of the stimulus book has been re-formatted to allow the examiner to turn pages without reaching across the table
