Illinois General Assembly - Illinois Compiled Statutes

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(15 ILCS 335/4A) (from Ch. 124, par. 24A)

Sec. 4A.

(a) "Person with a disability" as used in this Act means any person who
is, and who is expected to indefinitely continue to be, subject to any of
the following five types of disabilities:

Type One:  Physical disability.  A physical disability is a physical
impairment, disease, or loss, which is of a permanent nature, and which
substantially limits physical ability or motor skills.  The
Secretary of State shall establish standards not inconsistent with this
provision necessary to determine the presence of a physical disability.

Type Two:  Developmental disability. Developmental disability means "developmental disability" as defined in Section 1-106 of the Mental Health and Developmental Disabilities Code.  The Secretary
of State shall establish standards not inconsistent with this provision
necessary to determine the presence of
a developmental disability.

Type Three:  Visual disability.  A visual disability is blindness, and the term "blindness" means central vision acuity of 20/200 or less in the better eye with the use of a correcting lens.  An eye that is accompanied by a limitation in the fields of vision so that the widest diameter of the visual field subtends an angle no greater than 20 degrees shall be considered as having a central vision acuity of 20/200 or less.  The Secretary of State shall establish
standards not inconsistent with this Section necessary to determine the
presence of a visual disability.

Type Four:  Hearing disability.  A hearing disability is a disability
resulting in complete absence of hearing, or hearing that with sound
enhancing or magnifying equipment is
so impaired as to require the use of sensory input other than hearing
as the principal means of receiving spoken language. The Secretary of State
shall
establish standards not inconsistent with this Section
necessary to determine the presence of a hearing disability.

Type Five: Mental Disability. A mental disability is a significant impairment of an individual's cognitive, affective, or  relational abilities that may require intervention and may be a recognized, medically diagnosable illness or disorder. The Secretary of State shall establish
standards not inconsistent with this provision necessary to determine the
presence of a mental disability.

(b) For purposes of this Act, a disability shall be classified as
follows:  Class 1 disability:  A Class 1 disability is any type disability
which does not render a person unable to engage in any substantial gainful
activity or which does not impair his ability to live independently or to
perform labor or services for which he is qualified.  The Secretary of State
shall establish standards not inconsistent with this Section
necessary to determine the presence of a Class 1 disability.
Class 1A disability: A Class 1A disability is a Class 1 disability which
renders a person unable to walk 200 feet or more unassisted by another person
or without the aid of a walker, crutches, braces, prosthetic device or a
wheelchair or without great difficulty or discomfort due to the following
impairments: neurologic, orthopedic, oncological, respiratory, cardiac, arthritic disorder, blindness,
or the loss of function or absence of a limb or limbs. The Secretary of
State shall establish standards not inconsistent with this Section necessary
to determine the presence of a Class 1A disability.  Class 2
disability:  A Class 2 disability is any type disability which renders a
person unable to engage in any substantial gainful activity, which
substantially impairs his ability to live independently without
supervision or in-home support services, or which substantially impairs
his ability to perform labor
or services for which he is qualified or significantly restricts the
labor or services which he is able to perform.
 The Secretary of State shall
establish standards not inconsistent with this Section necessary to
determine the presence of a Class 2 disability.
Class 2A disability: A Class 2A disability is a Class 2 disability which
renders a person unable to walk 200 feet or more unassisted by another
person or without the aid of a walker, crutches, braces, prosthetic device
or a wheelchair or without great difficulty or discomfort due to the
following impairments: neurologic, orthopedic, oncological, respiratory, cardiac,
arthritic disorder, blindness, or the loss of function or absence of a limb
or limbs. The Secretary of State shall establish standards not inconsistent
with this Section necessary to determine the presence of a Class 2A
disability.
