Maximum head shall be at least 15 ft.

Student Curriculum: The curriculum shall consist of one (1) set of 5 Learning Activity Packets The student curriculum shall contain at least 26 industry skills covering centrifugal pump operation, seal maintenance, applications, installation, maintenance, troubleshooting, performance analysis, and component selection.

The student curriculum supplied shall be designed in a skill-based format that focuses on teaching industry-relevant tasks.

The objectives shall be accomplished by organizing the learning material into a series of learning activity packets, which are further subdivided into three or more segments per packet.

All learning materials needed shall be contained in the packets including text material, laboratory equipment activities, and multimedia directions.

No external text sources shall be required.

The specific cognitive skills taught by each text passage shall be identified next to the passage.

Each lab activity shall be identified by the industrial task taught.

All activities shall be highly detailed with step-by-step instructions to facilitate a self-directed learning environment.

A combination of step-by-step enabling activities and creative, problem-solving activities shall be provided.

A self-review of five to ten questions shall be provided after each segment.

The curriculum must be capable of both self-directed and instructor directed study.

All activities must correlate directly to the hardware supplied, with detailed illustrations and diagrams.
