TSSB-Recognized Skill Standards May 22,
2007
Background
This skill standards development project
was initiated by Del Mar Community College
in January, 2007, as part of a TSSB
curriculum development initiative under the
auspices of the Texas Higher Education
Coordinating Board, in which education
applicants develop and achieve TSSB
recognition for skill standards and meet
the requirements for program recognition in
order to qualify for an incentive grant of
$15,000 from federal Perkins Leadership
funds.
The Geographic Information Systems (GIS)
Technician skill standards address a
growing demand for specialists to help
design, develop, and coordinate integrated
geographical information system databases
of spatial and non-spatial data. These
technicians decide effective presentation
of information and create digital maps and
graphs using GIS software and related
equipment.
There is currently no Bureau of Labor
Statistics classification for the GIS
occupational area. The U.S. Department of
Labor Occupational Outlook Handbook,
2006-2007 Edition notes that "a new type of
mapping scientist is emerging from the
older specialties of photogrammetrist and
cartographer; the geographic information
specialist combines the functions of
mapping science and surveying into a
broader field concerned with the collection
and analysis of geographic data." There is
a substantial demand for technicians in
geospatial information technology, for
individuals who do not wish to pursue an
advanced degree, according to the American
Society for Photogrammetry and Remote
Sensing. The Institute for Advanced
Education in Geospatial Sciences indicates
that "recent research has shown that almost
every government agency reported to The
Senate Governmental Affairs Subcommittee on
International Security, Proliferation and
Federal Services (Assessment 2001) has an
immediate need for additional training in
the geospatial sciences. Of the 18 agencies
surveyed, 16 reported training or workforce
needs in this area" and that "the current
industry growth in remote sensing and
geospatial sciences has created an unmet
demand for industry experts able to work
and develop within these fields."
Project Goals
The project goals were:
-
Identify voluntary skill standards for
the GIS technician occupational area to
serve as benchmark for entry into this
occupational area and to serve as guides
for curriculum development of community
and technical college programs of study
that will effectively meet the needs of
both the newly graduated entry-level
worker and the seasoned professional
returning to education to upgrade his or
her workplace skills.
-
Publish and promote the results and
support the use of skill standards by
educators, businesses, unions, students,
workers, and government agencies.
Development and Validation Methods
A job analysis was conducted in December,
2004 in San Diego, California, with the
participation of a panel of GIS analysts,
specialists, and coordinators all
representing city and county government in
and around the San Diego area. This job
analysis is recognized as the most
comprehensive prepared as of the date of
this publication. The resulting job
analysis, or DACUM (Developing a
Curriculum), produced a chart of
occupational duties and tasks. This DACUM
was validated in Texas in 2005 during a
project to revise existing GIS courses and
create new courses to be offered in
community colleges across Texas, including
Del Mar Community College's Associate of
Applied Science degree. This skill
standards development project utilized the
validated DACUM to identify and develop
skill standards elements.
The GIS Technician skill standards were
developed and validated by a panel of
subject matter experts (SMEs) from Texas
and California. The panel included
representation from Texas private industry,
education, and state government.
Duties and tasks were transcribed from the
DACUM as Critical Work Functions (CWFs) and
Key Activities (KAs), respectively. The
SMEs validated that the DACUM elements were
transcribed and aggregated accurately. SMEs
worked to develop performance criteria for
each of the KAs.
The SMEs also defined knowledge, skills,
and conditions (tools) for each of the KAs.
The knowledge, skills, and conditions that
50% or greater of the respondents indicated
as necessary to each KA were included in
the skill standards.
Finally, SMEs rated the complexity of each
of seventeen academic and employability
skill areas on a scale of 1 to 5 (with 1
indicating low complexity, and 5 indicating
high complexity). The average of the
responses was used to indicate the
complexity level the CWF required of each
knowledge or skill area.
In any skill standards development effort
it is critical to consider the views of all
of the participants to ensure that the
outcome reflects a truly consensus-based
effort. During this project there was
concern about what constitutes a
performance criteria statement. The
Geographic Information Systems body of
knowledge publication defines performance
criteria in a format different than the
performance criteria format required for
TSSB skill standards recognition. In order
to comply with requirements for
recognition, the SMEs worked to develop
performance criteria that conformed to TSSB
required format.
The GIS Technician skill standards contain
ten critical work functions in the areas of
creating and/or acquiring GIS data;
maintaining GIS data; conducting spatial
and non-spatial analysis; generating GIS
products; developing software applications;
managing GIS data; providing technical
support; performing administrative tasks;
and pursuing professional development.
