The primary reason for being denied INCOSE Certification is that a review team has been unable to confirm that you meet the experience requirements based on your application, references, or interview (ESEPs). If you wish to reapply, you are advised to review the shortfalls noted in your denial letter and address those before submitting a new application. You will have to pay a new application fee. 

If you apply for ESEP and are denied, you will be given the opportunity to apply for CSEP without having to pay an additional fee. You will still need to meet the requirements for CSEP, including passing the knowledge exam. 

If you apply for CSEP and are denied, you may become an ASEP after you pass the knowledge exam. 

If you believe that the process of reviewing your certification application was not followed correctly, you may submit an appeal. This is not an opportunity to submit additional information or to disagree with the assessment.
