School year. The year recorded is always the one that corresponds to the end of the year. For example, '2015' (or '15') is used when referring to the 2014-2015 academic year.

1. Years are grouped according to whether they have the same score ranges for each grade and achievement level. For example, the reading achievement ranges are the same for years 2000-2002, so they form a year group. 2. A table was created by hand from the 2000-2008 NCERDC documentation files. It contains a row for each grade and achievement level. The columns indicate the minimum and maximum values for each year group. 3. For each year group, grade and achievement level, calculate the difference between the min and max values. This tells us how many possible score values there are per year, grade and achievement level. Similarly, calculate the min/max range for 2008 scores. Example: 2000 min/max difference is 16 (130-114); 2008 min/max difference is 28 (330-302); 4. Calculate the increment to be used when adjusting an original score to a 2008 score. The increment is the ratio of the min/max difference in a year group to the min/max difference in the base year (2008). In other words, for every increase of 1 in the score of an earlier year, what is the equivalent increment in 2008? Example: Ratio (increment) = 28/16 = 1.75; 5. For every score value in the earlier year, calculate the 2008 equivalent. The original min value’s equivalent is the min value in 2008 for the same grade and achievement level. Same for the max values. All values in between the min and max are converted by starting with the 2008 min value, and applying the increment as shown in the table below. The values were rounded to the nearest integer.

Number of addresses at which the student lived during the indicated school year.

Census 2000 Block Group for Child Address (1). If a student is associated with more than two different block groups, all block groups are deleted. This affects a negligible number of records, and there is no way to determine which addresses should be used.

Census 2000 Block Group for Child Address (2). Populated if the student is associated with more than 1 block group during the school year. If a student is associated with more than two different block groups, all block groups are deleted. This affects a negligible number of records, and there is no way to determine which addresses should be used.
