This document serves as a supplemental guideline for the Classroom Accessibility Standards (CAS), and will further the rationale for many of the standards listed. The information presented will discuss the importance of each benchmark in the CAS standards.
Please note: This document, and the supporting CAS standards list, does not reflect all the 2010 ADA standards, but merely items pertaining specifically to general purpose classrooms. The 2010 ADA Standards for State and Local Government facilities (hereafter, “the 2010 ADA Standards”) provides the backbone for our accommodation requirements in State University of New York classrooms. Per the compliance information in the 2010 ADA Standards, should construction begin after March 15, 2012 (IE, new construction), the 2010 ADA standards should be followed. Buildings with no renovations post March 15, 2012 can follow the 1991 standards OR the 2010 standards; both of which make similar provisions.
For additional information, please review the following reference: 2010 ADA Standards for Accessible Design may be reviewed at this website. To add, a comprehensive comparison of the standards may be found at Comparison of the 2010 and 1991 ADA Standards for Accessible Design (PDF).
Designing a lab that is universally accessible begins with the physical environment of the facility. Considerations for making a computer lab facility more accessible include the following:
To begin the process of making your computer lab accessible to everyone, take the following steps.
The following are guidelines for equipment, software, signage, and other elements in computer labs on campus. Although these are guidelines, all equipment and other elements in the computer lab must comply with the Temple University policy on Accessible Information and Technology:
Any information and technology — including, but not limited to, computers and ancillary equipment, instructional materials, software, videos, multimedia, telecommunications, or web-based content or products — developed, procured, maintained, or used in carrying out university activities must be compliant with Sections 504 and 508 of the Rehabilitation Act of 1973, as amended, the Americans with Disabilities Act of 1990, as amended, and other related local, state, and federal laws, as well as other related university policies.
It was required that the items needing remediation be corrected before the start of the Fall 2015 semester.
Signs should be printed with the following attributes:
If accessibility symbols are used, they should be the international accessibility symbols.
Signs with tactile characters (Braille) should be positioned so that the baseline of the lowest character is 48” above the floor and the baseline of the top character is a maximum of 60” from the floor. Visual characters must be at least 40 inches from the floor.
Documentation should be available in both print and braille, and should be positioned no more than 48” above the floor.
An alternative to putting braille on signs around the lab is to have an HTML or Word document available in the 'Accessibility Tools' folder labeled 'policies and guidelines.' Electronic copies of the documentation are an acceptable alternative to braille documents.
Counters should be considered service counters such as where a student would sign in/out equipment, log books, Pay to Print swipe to release PC station, etc. Surfaces where they perform the majority of their work, such as desks and tables, would be considered a work surface and are discussed in subsequent sections.
Counters should have at least one section that’s at an acceptable height for patrons in wheelchairs or scooters, at most 36” from the floor, and at least 36” wide (30" wide if approached from the front; otherwise should be adjacent to a walking surface that is at least 30” by 48”). If writing is required (for example: sign in/out log), then the height should be between 28” and 34” from the floor.

Figure 1– Toe and knee clearance for front approach counters (click to enlarge)
Forward approach counters must have knee and toe space under the counter (at least 30” wide, and extending 17” under the counter with a height of 27” above the floor, which a toe clearance of 6” beyond the knee clearance at a height of 9” above the floor).
At least one Pay to Print (aka UniPrint) station for each format of printer (i.e. standard desktop printer vs. plotter) should be located so they are wheelchair accessible (see counter requirements).
The Pay to Print station should be a PC based station that has the NVDA screen reader installed, and it should have the option to adjust the contrast.
Access to output trays/bins for printers managed by an accessible Pay to Print station is between 15” and 48” from the floor (between 24” and 40” preferred) and 20" to 25" from the center of where the person’s lap is expected to be.
It may not be feasible for a department to deploy accessible hardware on every computer in every lab. However, there are minimum numbers of accessible stations that need to be in each lab.
For each type of computer (i.e. PC, Mac, CAD Station, Scanning Station, and Breakout room) in the lab, the number of accessible stations of that type should adhere to the following chart:
| Number of unique type STATIONS | Minimum number of required accessible workstations |
|---|---|
| 1 to 25 | 1 |
| 26 to 50 | 2 |
| 51 to 150 | 4 |
| 151 to 300 | 5 |
| 301 to 500 | 6 |
| 501 to 5000 | 6, plus 1 for each 150, or fraction thereof, between 501 through 5000 |
Ideally the accessible stations will be spread throughout the room, rather than grouped together, unless the computers of that type are typically grouped together. The workstations with assistive technology should be designated with the international handicapped symbol.
There are four elements to consider with the physical dimensions of the work surface:

Figure 2 - work surface requirements (click to enlarge)
Clear aisle width between the work surface and a barrier should be at least 48”, with 60” recommended. A minimum of 60" is required for turning. Clear path to the workstation is at least 36" wide (the path can narrow to 32" at a point).

Height adjustable work surface with the following attributes:
The following software is required for the accessible workstations:
On every accessible workstation, there must be a readily available folder, or shortcut to the folder, called "Accessibility Tools" with the designated accessibility icon.
The new consultant training process should include training on how to use the accessible hardware and software, and on serving customers with disabilities.
The relevant sections of Section 508 of the Rehabilitation Act of 1973 may include: subpart B 1194.26 for workstations and subpart B 1194.25 for Pay to Print stations. Relevant sections of the 2010 ADA Standards for Accessible Design may include: 304, 305, 306, 308, 309, 703, 802, 902, and 904.
