What is an EDI 188?

The EDI 188 Educational Course Inventory is the ANSI X12 transaction set used by schools, school districts and postsecondary institutions to request and transmit information about educational courses currently or previously offered.

Course information, such as titles, descriptions, credits and levels, helps receiving institutions evaluate transcripts and award transfer credit. State agencies also use course inventories for reporting and to check that courses meet requirements. Inventories can cover current and historical courses, which matters because transcripts often list courses no longer offered, and institutions need their descriptions to evaluate them.

How to read this diagram: the top row shows who sends the 188, to whom, and which documents usually come before and after it. The lower part shows what X12 release 008010 itself requires: the envelopes around the 188 and the segments and loops the standard marks as required, area by area. Optional loops are listed by the segment that starts them rather than drawn in full. This is the standard's minimum, not a trading partner's requirement: each partner's implementation guide usually makes some optional loops mandatory, restricts the codes and may use a different release.

Structure

Mandatory segments in the 188 (X12 release 008010)

The segments X12 release 008010 marks as mandatory at their level, in order. Segments inside optional loops are needed only when the loop is used. This is the standard's requirement, not your trading partner's: each partner's implementation guide names the release it uses, adds the optional segments it requires and restricts the values. The requirement status comes from one published X12 reference listing and has not been checked against a second source.

Practical example

The 188 in practice

A university evaluates transfer credit for students from a community college. It requests the college's course inventory, and the college sends a 188 with each course's code, title, description, credits and level. The university maps the courses to its own equivalents.

Implementation

Implementation considerations for the 188

  • Keep course codes stable over time where possible.
  • Include historical courses that appear on transcripts.
  • Update the inventory when courses change.
  • Align course data with transcripts (130).
