ONCC reserves the right to cancel the scores of any candidate who violates the Professional Examination Rules, or to cancel scores resulting from any testing irregularity.

Score Reports
Candidates will receive an official score report at the testing center, on screen and in print, indicating PASS or FAIL. Score reports will not be mailed to candidates. No numeric scores will be reported. Score reports also list the major subject areas of the test and the competency level the candidate has achieved on each. These levels may help failing candidates identify areas in which further study may be needed before retaking the test. The levels used are as follows:

• Level 1 The score obtained is well below competence level.
• Level 2 The score obtained is below competence level.
• Level 3 The score obtained is at competence level.
• Level 4 The score obtained is above competence level.

Passing Scores
The passing scores for the ONCC tests were established via a systematic procedure (a Passing Score Study) that employed the judgment of groups of oncology nursing professionals representing various geographical areas, practice settings, roles, and subspecialties. Because of ONCC's commitment to quality and test security, there are multiple forms of each certification examination.

ONCC and Pearson VUE develop the various forms of each test from the test blueprints, however, the level of difficulty of the forms may vary slightly because different questions appear on different forms. Because it would be unfair to require a candidate taking a slightly more difficult form of the test to answer as many questions correctly as a candidate taking an easier form, the statistical procedure known as equating is used to correct for differences in test difficulty. Equating is dependent upon a sufficient number of test candidates. If fewer candidates register than are required for accurate equating, another passing score study is conducted.

Certificates and Wallet Cards
ONCC will provide a personalized certificate and wallet card for each candidate who passes the test or meets the ONC-PRO requirements approximately 8 weeks after scores are reported. There is a $10 charge for a duplicate or replacement certificate and wallet card.
