NWEA sets the gifted benchmark at 95%:
The 95th percentile is a nationally accepted norm for identify students for placement in accelerated programs. NWEA strongly encourages districts to set TAG guidelines that meet the needs of their district. Districts can use percentile charts in the NWEA RIT Scale Norms publication to set any desired TAG guideline.
