Occupational prestige (also known as job prestige) is a way for sociologists to describe the relative social class positions people have. It refers to the consensual nature of rating a job based on the belief of its worthiness. The term prestige itself refers to the admiration and respect that a particular occupation holds in a society. Occupational prestige is prestige independent of the particular individual who occupies a job. Sociologists have identified prestige rankings for more than 700 occupations based on results from a series of national surveys. They created a scale with 0 being the lowest possible score to 100 being the highest, and then ranked the occupations based on the results of the survey.
People rate the 'general standing' of an occupation (the most common question). It is taken to be a measure of occupational prestige and hence of the social status of occupations. Many other criteria have been proposed, including 'social usefulness' as well as 'prestige' and 'status' themselves. In order to obtain the scale of occupations (which is invariably taken to be national in application), respondents' ratings are aggregated.
Job prestige did not become a fully developed concept until 1947 when the National Opinion Research Center (NORC), under the leadership of Cecil C. North, conducted a survey which held questions regarding age, education, and income in regard to the prestige of certain jobs. This was the first time job prestige had ever been researched, measured, and taught. Duncan's Socioeconomic Index (DSI, SEI)  became one of the most important outcomes of this survey, as it gave various occupational categories different scores based on the survey results as well as the result of the 1950 Census of Population. During the 1960s the NORC did a second generation of surveys which became the basis for the socioeconomic status (SES) score until the 1980s as well as the foundation for Trieman's International Prestige Scale in 1977. Out of these surveys and research job prestige has been defined in various ways. Some definitions include:
Different people seem to weight these issues differently in their understanding of prestige. Most people seem to implicitly view prestige as a weighted average of income and education and this is the operational definition used in indices like DSI and ISEI. However other people (especially in the working class) seem to have more moralized notions of how much a job helps society and would, for instance, rate doctors high and lawyers low even though both jobs require postgraduate degrees and earn high incomes.
The indicators most commonly used to measure SES come from Duncan's (1961) Socioeconomic Index (SEI), a composite of occupational prestige, income, and education. Duncan used data from North and Hart's study of 1949 occupational prestige and census data  to conduct the first correlational study of the statistical relationship between education, income, and occupation. Duncan focused on white males with at least a high school education and income of $3,500 dollars or more in 1949, and found correlations among income, public-ranking of occupational prestige, and educational level of around 0.75. The study did not report whether the index included a sample of ethnic minorities.
The SEI model continues to influence the way researchers measure SES. The National Educational Longitudinal Study (NELS:88, NCES, 1988) initially employed a measure of SES developed by Stevens and Featherman (1981) based on father's income, mother's income, father's education, mother's education, and father's and mother's occupation as rated by the SEI model. In the first-year follow-up study, the National Center for Education Statistics (1990) used the Nakao and Treas (1994) revised SEI model. 
During the 1960s through the 1980s job prestige was calculated in a variety of different ways. People were given index cards with about 100 or so jobs listed on them and had to rank them from most to least prestigious. This ranking system was known as placing jobs in a "ladder of social standing." Another method they used in this time period was to have the respondents rank jobs on a "horizontal ruler" using specific guidelines such as estimated income, freedom of choice, and how interesting the job was. No matter what the method the outcomes were generally the same .
Although pay and fame have little to do with occupational prestige, the measures of prestige is a part of the concept of social economic status (SES). Job with high prestige are more likely to have a higher level of pay stability, better lateral career mobility, and established professional associations. Some popular scales that are used to measure SES include: the Hollingshead's four and six measure of Social Economics Status Scale, the Nam, Boyd, and Power scale, and the Duncan's measures of Social economics.
A 2007 Harris Poll of 1,010 U.S. adults suggested that occupational prestige is linked to perceived impact on welfare; the highest ranking jobs being firefighter, scientists, and teachers. Lower ranking jobs include well-paid positions such as brokers, actors and bankers. Police officers and Engineers tended to fall somewhere in the middle of the ladder. According to The Harris Poll (2007), the following are the changes over the last quarter century of American's view as the most and least prestigious jobs:
