Additional Preparation and Information

A combination of Oracle training and hands-on experience (attained via labs and/or field experience) provides the best preparation for passing the exam.

This is a novice-level exam for candidates who are students at secondary schools, 2-year colleges and 4-year colleges and universities. If you are seeking a more career-level certification, you may consider purusing Oracle Database 12c Administrator Certified Associate or Oracle Database 11g Administrator Certified Associate. Those exams are more appropriate for candidates who have completed training though Oracle University or Oracle’s WDP program.
