This can get a bit complicated.
It's my understanding that as long as the student graduates without alternative assessments and meets the curriculum requirements, an IEP student would graduate with a regular diploma.
This also involves a transition plan. From

Transition Planning Checklist
While IDEA 2004 provides the legal requirements for transition services to support your childs goal of employment in the community or further education, there are several things that parents and students must do to prepare for life after high school.
Confirm the date of your childs graduation. Federal law states that your child's eligibility for special education ends when s/he graduates from high school with a regular diploma or until the child reaches the age of eligibility for a free appropriat education under State law.
Clarify whether your child will receive a regular high school diploma or a certificate of attendance....

Comment: A few commenters
recommended requiring parents to be
informed in writing of the consequences
of their child taking an alternate
assessment, including any effect on the
childs eligibility for graduation with a
regular high school diploma. The
commenters stated that providing this
information to parents is particularly
important in States that require passing
a State exam in order to obtain a regular
high school diploma.
Discussion: Section 612(a)(16) of the
Act requires that the State (or, in the
case of a districtwide assessment, the
LEA) develop and implement guidelines
for the participation of children with
disabilities in alternate assessments,
including alternate assessments aligned
to alternate achievement standards
permitted under 34 CFR 200.1(d).
Section 200.6(a)(2)(iii)(A)(2) of the
ESEA title I regulations requires States
to inform parents that their childs
achievement will be measured against
alternate achievement standards.
We acknowledge that these
requirements do not specifically require
a public agency to inform parents of any
potential consequences of a child
participating in an alternate assessment.
The commenters recommendation will
be considered along with other
comments we have received in response
to the NPRM proposing changes to
§ 300.160, which was published in the
Federal Register on December 15, 2005
(70 FR 74624). As noted elsewhere in
this preamble, the final regulations for
§ 300.160, regarding participation in
assessments, will be published in a
separate final rule.
Changes: None.
There are no IEPs for college students, however, Section 504 does cover students with disabilities. It's quite different from the level of support that can be expected in college vs public schools.
Also, a college student has to qualify for 504 accommodations. You might want to do some research via several different Universities' websites to get an overview of the process.
IEP mean Individual Education Plan, so I'm not sure what you mean by being treated different. By students? By teachers? By administration?
My thoughts are kudos to difficult child's high school. I find it amazingly refreshing that a high school would approach a student with supports that can be afforded via an IEP. I see too many that just want student's to age out or drop out if they are having difficulty.
In that difficult child has been offered this opportunity, there must be a need. I would go forward with-the IEP evaluation.
If they want her evaluated and she refuses, I suspect she'll have a hard time graduating, and may end up frustrated and drop out of school when maybe even a little bit of help and/or support will help her achive her goal -- college.
Be sure and click on the url above and read it (wrightslaw). I'd also call whoever is requesting the evaluation and get additional information. Check your SEA regs regarding regular diploma requirements.
