Term Codes and Sequence IDs - PERLMSU/ProjectPathways GitHub Wiki

Term Codes

Term codes are denoted by the semester and the last two digits of the of the year:

code description
FS Fall Semester
SS Spring Semester
US Summer Semester

Thus FS09 indicates "Fall Semester 2009".

Converting to numerical data for sorting

The FS, SS, US format is not useful for sorting thus the following conversions follow:

code description conversion
FS Fall Semester remove 'FS', append '.9'
SS Spring Semester remove 'SS', append '.3'
US Summer Semester remove 'US', append '.6'

Sequence IDs

Sequence IDs are four digit integers (x1x2x3x4) that also provide a timestamp for when a course was attempted by a student:

x1 x2x3 x4
The first digit indicates millenium, 0 for pre-2000, 1 for 2000 and later the middle two digits are the last two digits of the current year The last digit indicates term, 2 for summer, 4 for fall, 6 for spring
