# When were the scales normed? Are there plans to re-norm any time soon?

Update 2026:  We are currently in the process of renorming.  This will probably take a couple of years, but we will have new norms once this process has been completed.

Before 2026: ASEBA scores have shown little change for population samples obtained in different decades in the U.S. (T. Achenbach et al., School Psychology Review, 2002, 428-442; Journal of Emotional and Behavioral Disorders, 2002, 194-303; Journal of Abnormal Child Psychology, 2003, 1-11); Holland (N. Tick et al., Acta Psychiatric Scandinavica, 2007, 473-483; Social Psychiatry and Psychiatric Epidemiology, 2008, 349-355; Journal of the American Academy of Child and Adolescent Psychiatry, 2007, 1333-1340); Norway (Jozefiak et al., Nordic Journal of Psychiatry, 2012, 311-319); Japan (M. Kawauchi et al, Psychiatrica et Neurologia Paediatrica Japonica, 2011, 143-155); and Denmark (J. Henriksen et al., Danish Medical Journal, 2012, A4462).

The previous norms were from the year 2000.
