OWL Sections are presented at varying levels of difficulty based upon examinee performance. The examinee's achievement level is computed as the average of the levels for the two highest-level sections that the examinee passed (Lp1 and Lp2) where N is the total number of possible Levels. Zeros are substituted for either or both of these levels if the examinee passed fewer than two sections.

Performance Level Achieved = (Lp 1 + Lp 2) / N
