RBANS has reasonable test-retest reliability in schizophrenia.

Main results The RBANS was sensitive to cognitive impairment in schizophrenia. People with schizophrenia had scores about 30 points lower than the comparison group. Testretest reliability correlations were 0.84 for people with schizophrenia and 0.77 for controls. Mean differences in retest scores were small across the two study groups (none greater than 4 points). (Note from authors: The article provides base rate data on test-retest differences to guide clinical decision-making about cognitive change that can be applied to single case data).
