Terminology
History
In the early 1990s, the acronym STEM was used by a variety of educators in preference to SMET, including Charles E. Vela, the founder and director of the Center for the Advancement of Hispanics in Science and Engineering Education (CAHSEE). Moreover, the CAHSEE started a summer program for talented under-represented students in the Washington, DC area called the STEM Institute. Based on the program's recognized success and his expertise in STEM education, Charles Vela was asked to serve on numerous NSF and Congressional panels in science, mathematics and engineering education; it is through this manner that NSF was first introduced to the acronym STEM. One of the first NSF projects to use the acronym was STEMTEC, the Science, Technology, Engineering and Math Teacher Education Collaborative at the University of Massachusetts Amherst, which was founded in 1998.
In 2001, at the urging of Dr. Peter Faletra, the Director of Workforce Development for Teachers and Scientists at the Office of Science, the acronym was adopted by Rita Colwell and other science administrators in the

China
To promote STEM in China, the Chinese government issued a guideline in 2016 on national innovation-driven development strategy, instructing that by 2020, China should become an innovative country; by 2030, it should be at the forefront of innovative countries; and by 2050, it should become a technology innovation power.
In February 2017, the Ministry of Education in China has announced to officially add STEM education into the primary school curriculum, which is the first official government recognition of STEM education. And later, in May 2018, the launching ceremony and press conference for the 2029 Action Plan for China's STEM Education was held in Beijing, China. This plan aims to allow as many students to benefit from STEM education as possible and equip all students with scientific thinking and the ability to innovate. In response to encouraging policies by the government, schools in both public and private sectors around the country have begun to carry out STEM education programs.
However, in order to effectively implement STEM curricula, full-time teachers specializing in STEM education and relevant contents to be taught are needed. At present, China lacks qualified STEM teachers and a training system is yet to be established.
Several Chinese cities have taken bold measures to add programming as a compulsory course for elementary and middle school students. This is the case of the city of Chongqing.
Europe
Several European projects have promoted STEM education and careers in Europe. For instance, Scientix is a European cooperation of STEM teachers, education scientists, and policymakers. The SciChallenge project used a social media contest and the student-generated content to increase motivation of pre- university students for STEM education and careers. The Erasmus programme project AutoSTEM used automata to introduce STEM subjects to very young children.

Singapore
STEM is part of the Applied Learning Programme (ALP) that the Singapore Ministry of Education (MOE) has been promoting since 2013, and currently, all secondary schools have such a programme. It is expected that by 2023, all primary schools in Singapore will have an ALP. There are no tests or exams for ALPs. The emphasis is for students to learn through experimentation – they try, fail, try, learn from it and try again. The MOE actively supports schools with ALPs to further enhance and strengthen their capabilities and programmes that nurtures innovation and creativity.
The Singapore Science Centre established a STEM unit in January 2014, dedicated to igniting students’ passion for STEM. To further enrich students’ learning experiences, their Industrial Partnership Programme (IPP) creates opportunities for students to get early exposure to the real-world STEM industries and careers. Curriculum specialists and STEM educators from the Science Centre will work hand-in-hand with teachers to co-develop STEM lessons, provide training to teachers and co-teach such lessons to provide students with an early exposure and develop their interest in STEM.
Thailand
In 2017, Thai Education Minister Dr Teerakiat Jareonsettasin said after the 49th Southeast Asia Ministers of Education Organisation (SEAMEO) Council Conference in Jakarta that the meeting approved the establishment of two new SEAMEO regional centres in Thailand. One would be the STEM Education Centre, while the other would be a Sufficient Economy Learning Centre.
Teerakiat said that the Thai government had already allocated Bt250 million over five years for the new STEM centre. The centre will be the regional institution responsible for STEM education promotion. It will not only set up policies to improve STEM education, but it will also be the centre for information and experience sharing among the member countries and education experts. According to him, “This is the first SEAMEO regional centre for STEM education, as the existing science education centre in Malaysia only focuses on the academic perspective. Our STEM education centre will also prioritise the implementation and adaptation of science and technology.”
The Institute for the Promotion of Teaching Science and Technology has initiated a STEM Education Network. Its goals are to promote integrated learning activities and improve student creativity and application of knowledge, and to establish a network of organisations and personnel for the promotion of STEM education in the country.

In his 2012 budget, President Barack Obama renamed and broadened the "''Mathematics and Science Partnership (MSP)''" to award block grants to states for improving teacher education in those subjects.
In the 2015 run of the international assessment test the Program for International Student Assessment (PISA), American students came out 35th in mathematics, 24th in reading and 25th in science, out of 109 countries. The United States also ranked 29th in the percentage of 24-year-olds with science or mathematics degrees.
STEM education often uses new technologies such as RepRap3D printers to encourage interest in STEM fields.
In 2006 the United States National Academies expressed their concern about the declining state of STEM education in the United States. Its Committee on Science, Engineering, and Public Policy developed a list of 10 actions. Their top three recommendations were to:
*Increase America's talent pool by improving K–12 science and mathematics education
*Strengthen the skills of teachers through additional training in science, mathematics and technology
*Enlarge the pipeline of students prepared to enter college and graduate with STEM degrees
The National Aeronautics and Space Administration also has implemented programs and curricula to advance STEM education in order to replenish the pool of scientists, engineers and mathematicians who will lead space exploration in the 21st century.

In 2011, eleven percent of the U.S. workforce was black, while only six percent of STEM workers were black. Though STEM in the U.S. has typically been dominated by white males, there have been considerable efforts to create initiatives to make STEM a more racially and gender diverse field. Some evidence suggests that all students, including black and Hispanic students, have a better chance of earning a STEM degree if they attend a college or university at which their entering academic credentials are at least as high as the average student's. However, there is criticism that emphasis on STEM diversity has lowered academic standards.
Gender gaps in STEM
Although women make up 47% of the workforce in the U.S., they hold only 24% of STEM jobs. Research suggests that exposing girls to female inventors at a young age has the potential to reduce the gender gap in technical STEM fields by half. Campaigns from organizations like the National Inventors Hall of Fame aimed to achieve a 50/50 gender balance in their youth STEM programs by 2020.

on January 31, 2006, President George W. Bush announced the American Competitiveness Initiative. Bush proposed the initiative to address shortfalls in federal government support of educational development and progress at all academic levels in the STEM fields. In detail, the initiative called for significant increases in federal funding for advanced R&D programs (including a doubling of federal funding support for advanced research in the physical sciences through DOE) and an increase in U.S. higher education graduates within STEM disciplines.
The ''NASA Means Business'' competition, sponsored by the Texas Space Grant Consortium, furthers that goal. College students compete to develop promotional plans to encourage students in middle and high school to study STEM subjects and to inspire professors in STEM fields to involve their students in outreach activities that support STEM education.

The Department of Commerce notes STEM fields careers are some of the best-paying and have the greatest potential for job growth in the early 21st century. The report also notes that STEM workers play a key role in the sustained growth and stability of the U.S. economy, and training in STEM fields generally results in higher wages, whether or not they work in a STEM field.
In 2015, there were around 9.0 million STEM jobs in the United States, representing 6.1% of American employment. STEM jobs were increasing around 9% percent per year. Brookings Institution found that the demand for competent technology graduates will surpass the number of capable applicants by at least one million individuals.
According to Pew Research Center, a typical STEM worker earns two-thirds more than those employed in other fields.
Trajectories of STEM graduates in STEM and non-STEM jobs
According to the 2014 US Census "74 percent of those who have a bachelor's degree in science, technology, engineering and math — commonly referred to as STEM — are not employed in STEM occupations."
Updates
In September 2017, a number of large American technology firms collectively pledged to donate $300 million for computer science education in the U.S.
PEW findings revealed in 2018 that Americans identified several issues that hound STEM education which included unconcerned parents, disinterested students, obsolete curriculum materials, and too much focus on state parameters. 57 percent of survey respondents pointed out that one main problem of STEM is lack of students' concentration in learning.
The recent National Assessment of Educational Progress (NAEP) report card made public technology as well as engineering literacy scores which determines whether students have the capability to apply technology and engineering proficiency to real-life scenarios. The report showed a gap of 28 points between low-income students and their high-income counterparts. The same report also indicated a 38-point difference between white and black students.
The Smithsonian Science Education Center (SSEC) announced the release of a five-year strategic plan by the Committee on STEM Education of the National Science and Technology Council on December 4, 2018. The plan is entitled "Charting a Course for Success: America's Strategy for STEM Education." The objective is to propose a federal strategy anchored on a vision for the future so that all Americans are given permanent access to premium-quality education in Science, Technology, Engineering, and Mathematics. In the end, the United States can emerge as world leader in STEM mastery, employment, and innovation. The goals of this plan are building foundations for STEM literacy; enhancing diversity, equality, and inclusion in STEM; and preparing the STEM workforce for the future.
The 2019 fiscal budget proposal of the White House supported the funding plan in President Donald Trump's Memorandum on STEM Education which allocated around $200 million (grant funding) on STEM education every year. This budget also supports STEM through a grant program worth $20 million for career as well as technical education programs.
Events and programs to help develop STEM in US schools
In Vietnam, beginning in 2012 many private education organizations have STEM education initiatives.
In 2015, the Ministry of Science and Technology and Liên minh STEM organized the first National STEM day, followed by many similar events across the country.
in 2015, Ministry of Education and Training included STEM as an area needed to be encouraged in national school year program.
In May 2017, Prime Minister signed a Directive no. 16 stating: "Dramatically change the policies, contents, education and vocational training methods to create a human resource capable of receiving new production technology trends, with a focus on promoting training in science, technology, engineering and mathematics (STEM), foreign languages, information technology in general education; " and asking "Ministry of Education and Training (to): Promote the deployment of science, technology, engineering and mathematics (STEM) education in general education program; Pilot organize in some high schools from 2017 to 2018.
Women
Women constitute 47% of the U.S. workforce, and perform 24% of STEM-related jobs. In the UK women perform 13% of STEM-related jobs (2014). In the U.S. women with STEM degrees are more likely to work in education or healthcare rather than STEM fields compared with their male counterparts.
The gender ratio depends on field of study. For example, in the

in 2012 women made up 47.3% of the total, 51% of the social sciences, business and law, 42% of the science, mathematics and computing, 28% of engineering, manufacturing and construction, and 59% of PhD graduates in Health and Welfare.
In a study from 2019 it was shown that part of the success of women in STEM depends on the way women in STEM are viewed. In a study that researched grants given based primarily on project versus primarily based on the project lead there was almost no difference in the evaluation between projects from men or women when evaluated on project, but those evaluated mainly on the project leader showed that projects headed by women were given grants four percent less often.
Improving the experiences of women in STEM is a major component of increasing the number of women in STEM. One part of this includes the need for role models and mentors who are women in STEM. Along with this, having good resources for information and networking opportunities can improve women's ability to flourish in STEM fields.
LGBTQ+
People identifying within the group LGBTQ+ have faced discrimination in STEM fields throughout history. Few were openly queer in STEM; however, a couple of well-known people are

, the father of computer science, and Sara Josephine Baker, American physician and public-health leader.
Despite recent changes in attitudes towards LGBTQ+ people, discrimination still permeates throughout STEM fields. A recent study has shown that gay men are less likely to have completed a bachelor's degree in a STEM field and to work in a STEM occupation. Along with this, those of sexual minorities overall have been shown to be less likely to remain in STEM majors throughout college. Another study concluded that queer people are more likely to experience exclusion, harassment and other negative impacts while in a STEM career while also having fewer opportunities and resources available to them.
Multiple programs and institutions are working towards increasing the inclusion and acceptance of LGBTQ+ people in STEM. In the US, the National Organization of Gay and Lesbian Scientists and Technical Professionals (NOGLSTP) has organized people to address homophobia since the 1980s and now promotes activism and support for queer scientists. Other programs, including 500 Queer Scientists and Pride in STEM, function as visibility campaigns for LGBTQ+ people in STEM worldwide.

'', demographer Michael S. Teitelbaum criticized the efforts of the U.S. government to increase the number of STEM graduates, saying that, among studies on the subject, "No one has been able to find any evidence indicating current widespread labor market shortages or hiring difficulties in science and engineering occupations that require bachelor's degrees or higher", and that "Most studies report that real wages in many—but not all—science and engineering occupations have been flat or slow-growing, and unemployment as high or higher than in many comparably-skilled occupations." Teitelbaum also wrote that the then-current national fixation on increasing STEM participation paralleled previous U.S. government efforts since
