CLASS LABORATORY
210 Class Laboratory - Dry Area for material / data analysis or creative productions requiring common space. Dry lab can include sink but no fume hood which is considered a part of wet labs. Dry lab area is the primary function of the room.

A space used primarily for formally or regularly scheduled instruction (including associated mandatory, but non-credit-earning laboratories) that require special purpose equipment or a specific space configuration for student participation, experimentation, observation, or practice in an academic discipline. A space is considered to be scheduled if the activities generate weekly student contact hours (WSCHs), the activities fulfill course requirements, and/or there is a formal convener
present.
A class laboratory is designed for or furnished with equipment to serve the needs of a particular discipline for group instruction in formally or regularly scheduled classes. This special equipment normally limits or precludes the space’s use by other disciplines. Included in this category are spaces generally called teaching laboratories, instructional shops, computer laboratories, drafting rooms, band rooms, choral rooms, (group) music practice rooms, language laboratories, (group) studios, theater stage areas used primarily for instruction, instructional health laboratories, and similar specially designed or equipped rooms, if they are used primarily for group instruction in formally or regularly scheduled classes. Computer rooms used primarily to instruct students in the use of computers are classified as class laboratories if that instruction is conducted primarily in formally or regularly scheduled classes. Does not include Classrooms (110). Does not include informally scheduled or unscheduled laboratories (see Open Laboratory-220). This category does not include spaces generally defined as Research/Nonclass Laboratories (250). It does not include gymnasia, pools, drill halls, laboratory schools, demonstration houses, and similar facilities that are included under Special Use Facilities (Code 500 series). Computer rooms in libraries or used primarily for study should be classified as Study Rooms (410).
211 Class Laboratory - Computer Area  which is designated for the use of networked computers. Printers, scanners and other peripherals may augment the computer lab setup. OSU IT services such as telecommunication or networking routers would not be in computer labs. They are dedicated to computer use and are not banks of computers (as along a wall) that are shared with conventional classroom or office space.

Includes any space that directly serves a class laboratory. Included are projection rooms, telecommunications control booths, coat rooms, preparation rooms, closets, material storage (including temporary hazardous materials storage), balance rooms, cold rooms, stock rooms, dark rooms, equipment issue rooms, etc., if they serve class laboratories. Does not include service spaces that support a Classroom (see 115), Open Laboratory (see 225), or a Research/Nonclass Laboratory (see 255). Animal Facilities (570), Greenhouse (580), and Central Service (750) facilities are categorized separately.

OPEN LABORATORY
220 Open Laboratory - Dry Area for material / data analysis or creative productions requiring common space. Dry lab can include sink but no fume hood which is considered a part of wet labs. Dry lab area is the primary function of the room.

A laboratory used primarily for individual or group instruction that is informally scheduled, unscheduled, or open.
An open laboratory is designed for or furnished with equipment that serves the needs of a particular discipline or discipline group for individual or group instruction where 1) use of the space is not formally or regularly scheduled, or 2) access is limited to specific groups of students. Included in this category are spaces generally called music practice rooms, language laboratories used for individualized instruction, studios for individualized instruction, special laboratories or learning laboratories (e.g., speech, hearing, law, psychology, and health-related professions) if discipline restricted, individual laboratories, and computer laboratories involving specialized restrictive software or where access is limited to specific categories of students. For example, a computer laboratory with only engineering or CAD software or a computer-based writing laboratory available only to English Composition students would be classified as an open laboratory because of the restricted usage of the space for a particular discipline or discipline group. Spaces containing computer equipment that is not restricted to a specific discipline or discipline group are classified as Study Rooms (410) unless the primary intent is to function as a site for structured learning or group activities rather than individual knowledge acquisition. Laboratories with formally or regularly scheduled classes are classified as a Class Laboratory (210). This category also does not include spaces defined as Research/Nonclass Laboratory (250). A space that contains equipment (e.g., microcomputers), which does not restrict use to a specific discipline or discipline group and which is typically used at a student’s convenience, should be classified as a Study Room (410).

231 Individual Study Laboratory A room especially equipped and/or designed for individual student experimentation, observation, practice or study in a particular field of study.  Include rooms (which may have multiple stations) which serve a particular subject matter area. These rooms or stations are normally assigned to individuals for their own use.  This category does not include individual study facilities which are intended for general study purposes. 
232 Student Practice Room A specially equipped and/or designed room for group or individual student experimentation, observation or practice in a particular field of study.  Include music studios, speech practice rooms, small rooms used for practice by individual students or very small groups (a large room used for instruction of and practice by a group such as a band, orchestra, ensemble, etc., is usually classified as a class laboratory). This type of space is generally not assigned to any particular individual. A music studio assigned to a faculty member which serves as a combination faculty office and music studio should be classified as Faculty Office. This category does not include music studios which are generally larger than the music practice room and are designed to accommodate several persons at one time. 
Research/Nonclass Laboratory
250 Research/Nonclass Laboratory - Dry Area for material / data analysis or creative productions requiring common space. Dry lab can include sink but no fume hood which is considered a part of wet labs. Dry lab area is the primary function of the room.

A space used for laboratory experimentation, research, or training in research methods; professional research and observation; or structured creative activity within a specific program or for sponsored research (whether sponsored with federal, state, private, or institutional funds).
A research/nonclass laboratory is designed or equipped for faculty, staff, and students for the conduct of research and controlled or structured creative activities. These activities are generally confined to faculty, staff, and assigned graduate students and are applicable to any academic discipline. Activities may include experimentation, application, observation, composition, or research training in a structured environment directed by one or more faculty or principal investigators. These activities do not include practice or independent study projects and activities that, although delivering “new knowledge” to a student, are not intended for a broader academic (or sponsoring) community (e.g., a presentation or publication). This category includes laboratories that are used for experiments, testing, or “dry runs” in support of instructional, research, or public service activities. Nonclass public service laboratories that promote new knowledge in academic fields (e.g., animal diagnostic laboratories, cooperative extension laboratories) are included in this category. Student practice activity rooms should be classified under Open Laboratory (220). A combination office/music or art studio or combination office/research laboratory should be coded according to its primary use if only a single space use code can be applied. Determination also should be made whether the “studio” or “research lab” component involves developing new knowledge (or extending the application or distribution of existing knowledge) for a broader academic or sponsoring community (and not merely for the practitioner), or the activity is merely practice or learning within the applied instructional process. Primary use should be the determining criterion in either case. Does not include testing or monitoring facilities (e.g., seed sampling, water or environmental testing rooms) that are part of an institution’s Central Service (750) system. Also does not include the often unstructured, spontaneous or improvisational creative activities of learning and practice within the performing arts that take place in (scheduled) Class Laboratories (210) or, if not specifically scheduled, (practice) Open Laboratories (220). Such performing arts (and other science and nonscience) activities, which are controlled or structured to the extent that they are intended to produce a specific research or experimental outcome (e.g., a new or advanced technique), are included in the Research/Nonclass Laboratory (250) category.
251 Research/Nonclass Laboratory - Computer Area which is designated for the use of networked computers. Printers, scanners and other peripherals may augment the computer lab setup. OSU IT services such as telecommunication or networking routers would not be in computer labs.
