Welcome to the U.S. Postal Service:

* National Center for Employee Development

Introduction

Today's computerized mail processing equipment can read a printed address and sort over 35,000 letters an hour. The successful delivery of the nation's mail depends on such high technology processing systems, building support equipment, and postal veh icles. Managing these systems, operating them e fficiently, and keeping the equipment running are critical tasks for the postal workforce. The U.S. Postal Service's National Center for Employee Development (NCED), Norman, OK, is a high technology learning complex. It combines classrooms, labs, conferencing, housing, food, fitness, and health facilities in an educational, campus setting. The professional staff oversees and conducts courses for postal employees who ma nage and maintain major postal systems, vehicles, and mail processing equipment. The Center also delivers skills and inform ation programs for other employee groups.

*

contains about 45 classrooms and 23 labs, which vary with course delivery needs. High-technology labs and training equipment provide students with individual hands -on experiences. The lab and classrooms have raised computer flooring and movable walls that can be adjusted for equipment and program changes. Operational training elevators, boilers, and air conditioning systems were built into the facility design. Distance-learning broadcast booths, satellite broadcast studios, a printing/copying shop, and state-of-the-art audiovisual systems support the learning environment. The Center also leases three remote facil ities, totaling 86,000 square feet, primarily to conduct vehicle maintenance courses and some mail processing equipment programs.

Student Housing

The six-story, housing and recreation facility was added to the 62-acre, postal-owned site in 1992. The 445,000-square-foot housing faci lity contains 974, smoke-free guestrooms. It provides a comfortable living environment, re creation aimed toward fitness and health, and networking and teambuilding activities.

Postal Student Profile

Most NCED students are postal employees attending job-related training. They include electronics technicians, equipment mechanics, computer specialists, vehicle technicians, and other management and administrative emplo yees.

Food & Banquet Services

Two cafeterias offer three meals a day for students and conferees. The training center cafeteria will seat 300 at a time, and the hou sing facility cafeteria can accommodate 280. Banquets and other special food services are also available.

Non-Postal Offerings

The Center also offers some courses to nonpostal groups, and can develop customized programs. General courses cover heating and air conditioning controls, elevator maintenance, env ironmental health and safety, automotive maintenance, natural gas vehicle maint enance, conveyor controls, programmable logic controllers, networking technology, and office computer software. See the public Web site for details on pr ograms offered to non-postal clients.

Training Facilities

The main training facility is a 293,000square-foot, postal-owned building designed specifically for education. Built in 1988, it 3 U.S. Postal Service National Center for Employee Development, Norman, OK.

Fitness & Fun

On-campus fitness and recreation facilities provide healthful activities that contribute to the learning and meeting environment. Facilities include a gym, game rooms, a fitness center, an outdoor swimming pool, and outdoor playing fields and a walking track.

Health Care Services

The Center's on-site Health Clinic provides medical aid, emergency care, and health and wellness education for staff, students, and conferees. It is staffed by occupational health care nurses, and located in the housing facility. The Norman Regional Hospital is nearby if more extensive health care is needed.

? The Postal Satellite Training Network broadcasts live lectures and equipment demonstrations, via satellite, to post offices nationwide. When needed, equipment in local post offices is used for hands-on troubleshooting. Arrangements can be made to support satellite training or broadcasts for non-postal customers. ? NCED also uses video, computer, Internet, and other technologies to enhance courses, expand student access to them, and to condense training time.

Student Enrollment

Post offices enroll employees for training through a nationwide computer system linking them directly to the Center through the postal Intranet. Non-postal customers can get course and enrollment information at the external Web site, www.nced.com. Government pricing is available.

Professional Staff

About 500 postal and contract staff members support the Center operation. ? The training staff includes professional technical instructors, course design and delivery experts, computer network engineers, multimedia courseware developers, and administrative support specialists. ? Contract employees provide housing guest services, food service, housekeeping, security, facility maintenance, and groundskeeping.

Conference Facilities

Center conference facilities can accommodate groups of 50 to 850 in over 20,000 square feet of meeting and conference space. Available services include housing, meals and banquets, and state-of-the-art audiovisual support. The conference and meeting space is available for rent by postal, community, and business groups.

Advanced Training Methods

The NCED continually explores ways to improve training, and expand training capacities beyond the Oklahoma facility.
