My son was left off the ELC list that our district reported last year. It didn’t seem to make any difference, as he was admitted to the UCs to which he applied. He had the a-g requirements and was in the top 1-2% at the time they would have sent the ELC list.
(The only reason we found out he was off the list was that he didn’t receive an invitation to a UCLA event for ELC students that I saw mentioned here on CC.)
The only information we received was that “there was a computer error” in the district office. His HS counselor contacted the UC Office of the President, which said there is no way to add a name to the list after the deadline. But, they said that when the student completes the UC application, they are automatically reviewed for ELC and state context.
His counselor guessed that the glitch may have been related to him taking a number of dual enrollment classes on college campuses. But, that shouldn’t have made a difference for meeting the a-g requirements.
