NLSLSASD—National Longitudinal
School-Level State Assessment
Score Database
Description of fields used in the School and District Improvement Database:
The schooldata.org database provides test result fields and fields describing the
setting. The SMMBTGYY format for test result headers is used in the SchoolData.org
database. Briefly, these 8 characters are decoded as follows:
- S: Subject (M=Math, R=Reading, ...)
- MM: The measure (Ci=percent of students meeting or exceesing cut point i,
NT=number of tests.) Note that in addition to the cut points provided in the AIR
database 'CP' (percent passing) is also used.
- B: The student breakdown (T=All, W=White, B=Black, A=Asian, H=Hispanic, D=Economically
disadvantaged...)
- T: The test index (0 is the main test, some states offer more than one)
- G: The grade (G=2,..G=9 as expected and then 1=10, A=11, B=12)
- YY: The calender year at the end of the school year. (eg: `03` is the 2002-2003
school year)
