I think it depends on the environment. Many small to midsized colleges use some type of NAC for their dorms. Some of the most popular ones don't have support for IPv6. I know there are more, but here are a few:
NetReg (and it's commercial variants such as Infoblox Authenticated DHCP) ImpulsePoint Safeconnect Nomadix Gateway (used in many hotel guest networks)Cisco Clean Access when Inline mode (product is EOL but could explain why many schools couldn't do IPv6 in the dorms over the years)
In my specific case, we couldn't use 802.1x for wired ports until recently so we've always had to depend an IP based solution for NAC. In a dorm setting, where a lot of the wired hosts don't support 802.1x(Roku,printers,Bluray players) , options are limited . With newer switches supporting mac-address based authentication (MAB in Cisco world, Mac-Radius in Juniper), we can start planning for IPv6 in our dorms in at least a limited deployment.

Thank You for responding. If mid to small companies have equipment made in the last 7 years, they will not need to replace equipment. Most net admins at the mid to small companies have no idea about IPV6. Cost is a major consideration at the mid to small size companies, if they need to upgrade equipment. The difference between IPV4 and IPV6 for someone not familiar is huge, 1. There is a totally new format dotted decimal to colon. 2. The 32 bit to 128 bit is/or can be quite challenging for some net admins.

The companies at the mid size and smaller levels have to invest in newer equipment that handles IPV6.if they have gear made in the last 7yrs it's likely already got the right bits for v6 support, right?2. The network Admins at the above mentioned companies need to learn IPV6, most will want there company to pay the bill for this.for a large majority of the use cases it's just "configure that other family on the interface" and done.3. The vendors that make said equipment should lower the cost of said equipment to prompt said companies into purchasing said equipment.the equipment in question does both v4 and v6 ... so why lower pricing? (also, see 'if made in the last 7 yrs, it's already done and you probably don't have to upgrade')There is a huge difference between IPV4 and IPV6 and there will be a lot of'huge difference' ... pls quantify this. (unless you just mean colons instead of periods and letters in the address along with numbers)
