Cancer nursing is a dynamic specialty. The knowledge needed to provide care changes frequently. Maintaining your certification shows that your knowledge is up-to-date by combining an Individual Learning Needs Assessment (ILNA) with continuing education. Taking the assessment is the first step in preparing to renew by Option 1 (professional development points). After renewing your certification for the first time, you'll take an assessment based on the current test content outline before starting to earn points for your next renewal. The assessment identifies the number of points you'll need for renewal and the subject areas in which points must be earned. You can earn points for renewal by completing professional development in the subject areas indicated by your assessment results. You'll repeat this process for each subsequent renewal cycle.
