This is from the State of Tennessee Board:
What constitutes progressive engineering experience?
The Special Committee on Experience Evaluation of the National Council of Examiners for Engineering and Surveying (NCEES) has developed the following guidelines for the work areas and skills an engineer intern must develop to obtain progressive engineering experience. Board members utilize these guidelines when evaluating exam applications, with greater weight being given to the Practical Application of Theory component.
PRACTICAL APPLICATION OF THEORY
ANALYSIS--of operating conditions; performance assessment; feasibility studies; constructability; value engineering; safety; environmental issues; economic issues; risk assessment; reliability.
DESIGN--construction plan or specification preparation; product specifications; component selection; maintenance and social implications of final product.
TESTING--developing or specifying testing procedures; verifying functional specifications; implementing quality control and assurance; maintenance and replacement evaluation.
IMPLEMENTATION--of engineering principles in design, construction, or research; performance of engineering cost studies; process flow and time studies; implementation of quality control and assurance; safety issues; environmental issues.
SYSTEMS APPLICATION--evaluation of components of a larger system; evaluation of the reliability of system parts; design and evaluation of equipment control systems while considering ergonomics, utility, manufacturing tolerances, and operating and maintenance concerns; the engineering required to establish programs and procedures for the maintenance and management of buildings, bridges, and other types of structures where failure or improper operation would endanger the public health and safety.
TIME IN THE ENGINEERING PROCESS--difficulties of workflow; scheduling; equipment life; corrosion rates and replacement scheduling.
KNOWLEDGE AND UNDERSTANDING--codes, standards, regulations, and laws that govern applicable engineering activities.
MANAGEMENT OF ENGINEERING
Engineering management includes supervising staff, managing engineering projects, and managing and administering technology as it is applied in the field or in construction. It may involve:
PLANNING--developing concepts; evaluating alternative methods.
SCHEDULING--preparing task breakdowns and schedules.
BUDGETING AND CONTRACTING--cost estimating and control; contract development.
SUPERVISING--organizing human resources; motivating teams; directing and coordinating project resources.
PROJECT CONTROL--complete or partial project control.
RISK ASSESSMENT--assessment of risk associated with the progression of the project.
COMMUNICATION SKILLS
Accumulation of project knowledge through interpersonal communication with supervisors, clients, subordinates, or team interaction.
Transmission of project knowledge in verbal or written methods to clients, supervisors, subordinates, the general public, or team members. Examples would be via meetings, written reports, public hearings and reporting or findings and suggestions, other written correspondence and/or verbal briefings.
SOCIAL IMPLICATIONS OF ENGINEERING
Promoting and safeguarding the health, safety, and welfare of the public as demonstrated in daily work activities.
Demonstrating an awareness of the consequences the work performed may incur and a desire to mitigate or eliminate any potential negative impact.
Following a code of ethics that promotes a high degree of integrity in the practice of professional engineering.
I had to clarify my experience and followed this as an outline and it was accepted. MY NCCES record also follow this format and was eventually accepted, although they made me redo it a number of times.
