Interpretive Guide to Undergraduate Grading Systems

In order to give law schools a uniform basis for comparing applicants, LSAC converts grades earned at US institutions to a standard 4.0 system. These converted grades are included in your LSAC Academic Summary Report. 

How to Use LSAC’s Interpretive Guide to Undergraduate Grading Systems

LSAC’s Interpretive Guide to Undergraduate Grading Systems (IGUGS) shows how the grades on your Academic Summary Report compare to the grades represented on your institution’s transcripts.

You can search for schools in a few different ways:

  • To search by school code, type in a code and click Search. The school’s name and search results will appear.
  • To search by US state or Canadian province, select a state or province from the drop-down menu, then use the second drop-down menu to select a particular school and click Search. That school’s results will appear.
  • To search by school name, type the name of the school in the Enter School Name box. You may also type a portion of the name (e.g., “Saint” or “West”). All of the schools containing that name or phrase will appear in the Select School drop-down menu. If a particular university has more than one college or campus, they will all be listed in the Select School menu.
  • To search by US Institution Abroad, select a country from the drop-down menu, then use the second drop-down menu to select a particular US Institution Abroad and click Search. That school’s results will appear.

If the school has not provided grading-system information, a notice to that effect will appear.

A link to a list of regional accrediting bodies is included at the bottom of each Transcript Key screen. These accrediting organizations can provide further information about undergraduate schools.
