NEED Info ASAP - Is An Original Birth Certificate Required?

I am suppose to be on a bus to go to trucking school in the morning but in doing a last minute read over the multiple documents I was sent I found one that says I need to have my original birth certificate which I don't have. I am in California and need to know from those that have applied for your CDL permit/license if you were asked to present it or not.

 

No I dont have a passport. I did however read on the CA DMV site that if I have an original CA DL I dont need a birth certificate to apply for my CDL permit or license which I do have. Now I am just debating whether to get on the bus or not in the morning. The only reason I can think of why I would need it would be for the DMV but this is what it says on their site
"To apply for a commercial permit, you will need to:

Visit a DMV office (make an Appointment(s) for faster service)
Complete a California Driver License Driver License Application form (DL 44 or DL 44C). (An original DL 44C form must be submitted. Copies will not be accepted.)
Complete a 10 Year History Record Check form (DL 939) if you have been issued a driver license in the same or different name to operate any type of motor vehicle in another state or other jurisdiction within the previous ten years
Give a thumb print
Have your picture taken
Provide verification of your social security number. It will be verified with the Social Security Administration while you are in the office.
Verify your birth date and legal presence (you may use your California driver license) If your current name no longer matches the name on your birth date/legal presence document, see "True Full Name" and "How to Change Your Name" for more information.
Pay the application fee for a 5-year license
Pass a vision exam
Submit a completed Medical Examination Report form DL 51.
Effective October 1, 2004, DMV will accept only a Medical Examination Report (DL 51) with a revision date of 2/2004 or later, or a current medical form (containing the new blood pressure guidelines) approved by the Federal Highway Administration or the Federal Aviation Administration.
Pass the traffic laws and sign tests for the class of vehicle you will drive. You have three chances to pass the test."

So according to this I should not need it

 

I also read the TSA Hazmat requirements on their site which states my CA DL and SS card is sufficient for that which is required by the carrier that is sending me to trucking school. So other than them wanting it for people who are not CA state resident or do not hold a CA DL/ID I do not see why I would need it. Any other thoughts anyone?
