APPENDIX C Flow Diagrams Glossary of Terms Used in Comprehensive Flow Diagram The following definitions are listed in the approximate order of their appearance in progressive flow through the comprehensive flow dia- gram of the engineering community that was presented in Chapter 3. The definitions are divided by stages. ENTRY POOL that body of persons qualified and positioned to lie admitted to the U.S. higher-education system. U.S. Secondary Students all students enrolled in degree-granting programs in U.S. public and private secondary schools. Dropouts those U.S. high school students who did not pursue a program to completion. Noncollege those graduates of U.S. secondary schools who are not admitted within three years to a degree-granting program of higher education. Foreign Students Noncitizens who have been admitted to U.S. higher-education systems based on education pursued outside the United States. Reentering Adults past graduates of the U.S. secondary school system admitted to higher education after a three-year or longer lapse since graduation. EDUCATIONAL PREPARATION persons enrolled full time in U.S. higher-education institutions at all degree levels. 108

APPENDIX C 109 Engineering Students students enrolled in any engineering pro- grams leading to a B.S. or M.S. degree. Science/Math Students-persons enrolled in any program leading to a B.S. or M.S. degree in chemistry, physics, biology, mathematics, or computer science and related disciplines. Technology Students students enrolled in four-year technology programs leading to a B . S. or M. S . degree. Nontechnical Students all students enrolled in four-year degree- granting institutions who are not included as engineering/science/ math or technology students; all degree levels from bachelor's through Ph.D. are included in this group. Collegiate Below B.S.: Technical persons enrolled full time in programs granting less than a bachelor's degree in areas associated with engineering and science {for example, associate degrees or cer- tificates in areas such as electrical engineering technology, computer . . . programming, or instrumentation . Collegiate Below B.S.: Nontechnical All persons enrolled in pro- grams granting degrees below the bachelor's level who are not counted in the "Collegiate Below B.S.: Technical" category. Dropouts those enrolled students in any higher-education pro- gram who leave the program before graduation without a commit- ment to reenter or transfer to a different program. Engineering Ph.D. Students-students admitted to an accredited Ph.D. program who are actively working toward the degree. Science/Math/Technology Ph.D. Students students actively working toward the Ph.D. degree in chemistry, physics, biology, computer science, mathematics, technology, or related fields of study. Ph.D. Graduates students who have completed all requirements and been granted a Ph.D. degree. Ph.D. Nongraduates students leaving a Ph.D. program without completing all the requirements and being granted a degree. Foreign Ph.D. Students- noncitizens admitted to the Ph.D. pro- gram in U.S. schools based on credentials obtained in some other country. EMPLOYED IN ENGINEERING COMMUNITY persons employed in any pool in the engineering community. Engineer Pool that body of persons who meet the definition of engineer developed by the Panel on Infrastructure Diagramming and Modeling See Chapter 1~.

110 APPENDIX C Immigrant Engineers persons entering the engineer pool who qualify under the definition of engineer See Chapter 1) and whose educational preparation was in a foreign country. Engineering Faculty Pool persons holding budgeted full-time fac- ulty positions in degree-granting engineering departments, regard- less of degree level, rank, or tenure status. Staff Support that body of people, regardless of educational prep- aration, who occupy positions in direct managerial, financial, or other staff support areas to assist activities of the engineer, faculty, or technologist/technician pools. These people may or may not be qualified for these pools, but they are not currently functioning in any of them. Any person whose position is clearly within the engi- neering community by the nature of the services rendered should be classified as staff support. Such services include but are not limited to technical management, operations research, financial analysis, data processing, technical sales, procurement, and safety. Technologist/Technician Pool that body of persons who meet the definitions for technologist or technician formulated by the Panel on Infrastructure Diagramming and Modeling See Chapter 1 J . Immigrant Technicians persons entering the technologist/tech- nician pool whose educational preparation was in a foreign country. General Work Force persons entering the technologist/techni- cian pool leased on performance in the general work force or after internal training. These people may or may not have had higher educational preparation in the past. OUT OF ENGINEERING COMMUNITY those persons who have been either actual or potential members of the engineering community but are not currently employed in it. Technical Reserve Pool persons who by educational preparation, experience, or both are qualified With reasonable retraining) to func- tion in the engineering community but are presently outside it. Included would be such groups as unemployed engineers, retired persons, and technical graduates who never entered or have left engineering-related work. A "test" for the diverse group that makes up the technical reserve is this: Could this person with sufficient motivation E.g., financial, national emergency) be reasonably expected to enter or reenter the engineering community? Exit: Return to Home Country foreign graduates at any degree level who leave the United States for emigration or other reasons after graduation or a reasonable period for practical experience. Exit: Death, Disability, Emigration persons who were at one

APPENDIX C 111 time employed in the engineering community or were in the techni cal reserve and who are permanently lost to the system. Exit: Other Work persons who were potential entrants to the engineering community lay virtue of nontechnical or collegiate- below-B. S. degrees but who chose other fields of work. Labeling System for Flow Diagrams The labeling system for the detailed flow diagrams in Figure 3, Chap- ter 3, and in Diagrams A- 1 through F- 1 in this appendix is as follows: Label = Letter + 4 Digits The letter indicates one of six major categories of stocks and flows. A = Entry Pool B = Educational Preparation-B . S. /M. S. = EducationalPreparation- Ph.D. = Employed in the Engineering Community E = Exit from the Engineering Community F = Temporary Exit TechnicalReserve The first of the four digits represents a stock in one of the categories. {For example, B-2000 represents the pool of science and math students in the undergraduate educational system. ~ The second digit represents a flow into or out of one of the stocks and is followed by two zeros. For example, B-2200 represents the aggregated transfer of students into science and math from other curricula. B-2600 represents the flow of M. S. graduates out of science and math. A labeling convention was adopted whereby an aggregated flow from one stock to another bears the label of the originating stock. For exam- ple, in Diagram D-1, Flows of the Engineering Pool, the flow out of the engineer pool jD-lOOOJ into the staff support pool [D-3000) bears the label D-1700, but the counterflow into the engineer pool bears the label D-3 100. The third digit in the label represents a branch or disaggregation of a major flow and is followed loy a single zero. For example, in the label B-2310, B- denotes the educational preparation category; B-2 , the science/math student pool, a major flow; B-23 , in this case, transfers out; and B-2310, transfers to engineering. From the same source, transfers to technology would be labeled B-2330, and so on. The fourth digit represents a further disaggregation, and was neces- sary only in describing all the options in the entry pool.
