Leiter-3 – Standardization for Adults

One minute reading • Thursday, April 27, 2023

 

We are pleased to announce that another Leiter-3 test manual: Standardization for Adults has just been released.

 

Thanks to the research carried out and the development of norms for people aged 21-70+,  the Leiter International Performance Scale – Third Edition (Leiter-3) can be administered not only to persons aged 3 to 20 years (as before), but also to adults. 

 This is particularly valuable because the Leiter-3 designed to assess nonverbal intelligence, nonverbal memory and attention, as the only completely non-verbal test can be used to examine persons with whom verbal contact is difficult or impossible.  

 We are glad that by issuing the expected Standardization for Adults, we can respond to signals by psychologists that Leiter-3 would also be useful for examining people over 20 years of age.
