Percentile band is created by forming an interval one standard error of measurement above and below the obtained score and converting the resulting values to percentiles. Moreover, Percentile bands are range of percentile ranks in which a pupil/student is expected to fall on repeated testin. It is a way to indicate the error in scores to avoid over-interpretation of results.
