Global Assessment of Functioning 

The GAF or Global Assessment of Functioning is a scale intended to represent the continuum of Mental Health to Mental Illness.  The score represents the rater's opinion of the client's overall functioning in both psychological and social/occupational areas, while excluding impairment due to physical or environmental limitations .  

Besides being used as an indicator of level of functioning, the "Current" GAF gives a baseline to gauge functioning variation (e.g. past 30 or 90 days) while the "Highest GAF Past Year" might be a goal to work towards.  

Be careful to not let the "simplicity" of the scale let you forget the significance of accurately applying it.  Good "gaffing" helps us understand where an individual is at, it also is likely to be the foundation of service authorizations and outcome measurements.  Consider consultation if uncertain.
