I think you need to take the TEAS over again because the RN program requires ATI TEAS while the LPN program requires the TEAS PN. You can double check with ECC but I'm pretty sure they're both different tests.
I also received an email June 30. I'm pretty sure health insurance is mandatory for any nursing program. It's mentioned as a requirement in the fact sheet on the ECC website and also included in the packet they sent out with the acceptance letters.
