We need a generic name for that high we get. When I was in high school my friends and I talked about our “physics high” after we’d worked through a complicated physics homework problem.

Here is a reference from IIBA.org site about this question:

Contacts for many of the projects I have worked on over the past 7 or 10 years are no longer available. How do I document this in such a way that I can still get credit for the hours performed?

Please indicate the situation in the description field for the specific project in question (i.e., that you are not able to provide contact information for the person you reported to) and minimally, provide the name and contact information of a person who can verify your employment with that organization. However, this cannot be the case with all projects submitted as we need some projects for which we can validate the tasks, hours and dates with the appropriate contact for audit purposes.

Hilda,

Currently IIBA application does not have a way for you to submit proof of experiences other than listing your project information as well as contact information for person who can speak about your experience on the project. This person can be a manager, colleague… anyone who can speak about the tasks you performed during the projects. The spreadsheet I provided as well as our CBAP Application worksheet, only helps with organizing your time and identifying the areas where you need more hours, before submitting your application. It doesn’t take place of the application or your due diligence to ensure that the hours you put down are correct and can be verified.

Hilda,
You might want to get in touch with Linda Erzah (author of the post I linked to) for your CBAP application questions. I can only speak to my own experience and my application has not yet been submitted or approved yet. But the only “proof” I was asked for was a project contact and my understanding is that you only need proof if you are audited, and it’s mostly via contacting those project contacts.
