- Statistics that apply to a school year that spans two calendar years (e.g. 2005-2006) will be saved with only the
latter year in the
statistics.yearcolumn. - If a statistic record's
contiguousfield istrue, that means it can be compared to the previous year in a line graph. Some metrics may use a different calculation method from one year to the next, resulting in a time series where one year's value is not comparable with the previous. In this case, line graphs will need to either note the change or only use the most recent contiguous series of values.
- If a school ranking record has no associated school grade levels (i.e. a record in the
rankingstable withfor_school_districts==falsehas no associated records in therankings_gradestable), it is assumed that schools which teach any grade level are being ranked.
