Short Answer
Why is closing the Department of Education and returning the education
authority to the states expected to improve the quality of the school
system?
Closing the Department of Education isn't actually intended to return education authority to the state or to improve the quality of the school system. Few policy makers behind this proposal, who understand the department and what it does, actually believe this will happen, or even had that goal. These statements are purely window dressing.
Indeed, the Executive Order in question actually centralized authority over public education in the federal government to a completely unprecedented extent, after 46 years of minimally invasive department involvement in educational institutions that did not meaningfully impact their authority over the educational process.
This proposal is driven by ill-informed political symbolism and provides political red meat to a Republican base. This Republican base is skeptical that public education does any good, wants to advance factually false curricula to suit their political ideology, and wants to use the federal government to purge all tendencies that are perceived as liberal from both K-12 education and from higher education. Primarily, this Executive Order, in substance, is an effort to roll back decades of federal insistence that educational institutions protect the civil rights of their students.
The EO's focus on "ending DEI" which there is no legal authority for the President to enact, is trying to advance a pro-racist, pro-sexist, homophobic, and transphobic agenda in every education institution in the United States, with a longer term goal over undoing almost all of the accomplishments of the Civil Rights movements in the United States, and causing more students to develop politically conservative views.
Long Answer
What does the Department of Education do?
This question is based upon a false premise. The states have always had authority over education and this didn't change when the Department of Education was created. The notion that the federal department of education has taken authority over education away from the states is sophistry and simply isn't true.
The fact that there is a federal Department of Education leaves some uninformed people with the false impression that the federal government has much greater authority over state and local school systems than it does.
The Department of Education primarily administers various federal scholarships, federally sponsored student loans, and federal grants for various programs at both the K-12 level (mostly for special education and low income students — the school lunch program is administered by the Department of Agriculture), and the higher education level. It also enforces federal civil rights and privacy laws that apply to educational institutions.

About 13.7% of public school funding came from federal sources, 2021-22 school year, this is $2,500 per K-12 student came from federal funding (2021-2022 school year).
Incidentally, all ten of the U.S. states that rely most heavily on the federal government for public school funding (19.0% to 23.3%) are states that voted for President Trump in the 2024 election. All ten of the 100 largest school districts that rely most heavily on the federal government for school funding (23.2% to 48.6%) are also in states that voted for President Trump in the 2024 election.
Cuts to U.S. Department of Education programs are a notable example of ideology trumping traditional pork barrel budget politics that disproportionately hurts President Trump's base (much like his tariff policies).

The Department of Education employed around 4,200 employees last
September, according to the Office of Personnel Management, which
accounted for about 0.2% of overall federal employment last year—the
smallest staff of the 15 Cabinet agencies.
(Source)
About 1,500 of those employees administer a $1.6 trillion student loan debt portfolio. All of its other functions are performed by the Department of Education's remaining 2,700 employees.
But as noted below, about 2,000 of those employees have been laid off. Time will tell if these employees, like those in other agencies such as 6,000 Department of Agriculture employees, will be ordered to be reinstated by the courts. Also, some of those 2,000 employees left under illegally offered buy out offers which Congress has not authorized or funded.
Ending the department v. ending the programs it administers
The Department of Education itself is just a bureaucratic organization to administer federal programs that, before it was created in 1979, were administered by different federal agencies.
The important question is not really whether the Department of Education continues to exist. If the Department of Education were dissolved, but its programs were transferred to the Department of Health and Human Services and the Justice Department (which enforces other civil rights and privacy statutes outside of the education arena), this would be basically meaningless and purely symbolic.
What really matters is which, if any, of the laws and programs administered by the Department of Education will continue to exist, and which will be discontinued entirely.
For example:
Will the federal government continue to provide Pell Grants and other scholarships to low income college students?
Will the federal government continue to provide federally guaranteed or directly provided student loans to college students?
Will the federal government continue to provide special education aid to K-12 schools?
Will the federal government continue to provide grants to school districts with large numbers of low income students?
Will the federal government continue to provide English as a second language grants to K-12 schools?
Will the federal government continue to regulate educational privacy (a provision of law which President Trump has famously availed himself to keep his college transcripts and other educational records secret)?
Will federal civil rights laws applicable to educational institutions be repealed?
The President may have the authority to dissolve the Department of Education (although this isn't obvious as the Department of Education was established by a statute which the President doesn't have the authority to unilaterally repeal, and a Secretary of Education has been nominated and ratified by the U.S. Senate).
But the President certainly doesn't have the authority to repeal the programs that the Department of Education administers without Congressionally approved legislation. If the Department of Education is dissolved, the laws it is charged with administering have to be transferred to other government agencies until such time (if ever) that Congress repeals those programs.
Also, the situation is complicated by the fact that the President's Executive Order to shut down the Department of Education seems to contemplate laying off essentially all of its employees and makes no clear plans to transfer its responsibilities, that remain legal obligations of the federal government until Congress acts otherwise, to other agencies, although it does seem to acknowledge that the Department of Education can't be closed until this is addressed.
During the first two months of Trump's second term, the Department of Education has "already has shed around 2,000 staffers – nearly half its workforce – through layoffs and buyouts, and canceled dozens of research contracts."
Anti-impoundment orders from the courts in the last two months, however, across a wide variety of areas of federal government spending, have established that almost all of the research contracts cancelled have been cancelled illegally and will have to be reinstated.
The text of the Executive Order
The Executive Order itself states:
By the authority vested in me as President by the Constitution and the
laws of the United States of America, and to enable parents, teachers,
and communities to best ensure student success, it is hereby ordered:
Section 1. Purpose and Policy. Our Nation’s bright future relies on
empowered families, engaged communities, and excellent educational
opportunities for every child. Unfortunately, the experiment of
controlling American education through Federal programs and dollars —
and the unaccountable bureaucracy those programs and dollars support —
has plainly failed our children, our teachers, and our families.
Taxpayers spent around $200 billion at the Federal level on schools
during the COVID-19 pandemic, on top of the more than $60 billion they
spend annually on Federal school funding. This money is largely
distributed by one of the newest Cabinet agencies, the Department of
Education, which has existed for less than one fifth of our Nation’s
history. The Congress created the Department of Education in 1979 at
the urging of President Jimmy Carter, who received a first-ever
Presidential endorsement from the country’s largest teachers’ union
shortly after pledging to the union his support for a separate
Department of Education. Since then, the Department of Education has
entrenched the education bureaucracy and sought to convince America
that Federal control over education is beneficial. While the
Department of Education does not educate anyone, it maintains a public
relations office that includes over 80 staffers at a cost of more than
$10 million per year.
Closing the Department of Education would provide children and their
families the opportunity to escape a system that is failing them.
Today, American reading and math scores are near historical lows.
This year’s National Assessment of Educational Progress showed that 70
percent of 8th graders were below proficient in reading, and 72
percent were below proficient in math. The Federal education
bureaucracy is not working.
Closure of the Department of Education would drastically improve
program implementation in higher education. The Department of
Education currently manages a student loan debt portfolio of more than
$1.6 trillion. This means the Federal student aid program is roughly
the size of one of the Nation’s largest banks, Wells Fargo. But
although Wells Fargo has more than 200,000 employees, the Department
of Education has fewer than 1,500 in its Office of Federal Student
Aid. The Department of Education is not a bank, and it must return
bank functions to an entity equipped to serve America’s students.
Ultimately, the Department of Education’s main functions can, and
should, be returned to the States.
Sec. 2. Closing the Department of Education and Returning Authority
to the States. (a) The Secretary of Education shall, to the maximum
extent appropriate and permitted by law, take all necessary steps to
facilitate the closure of the Department of Education and return
authority over education to the States and local communities while
ensuring the effective and uninterrupted delivery of services,
programs, and benefits on which Americans rely.
(b) Consistent with the Department of Education’s authorities, the
Secretary of Education shall ensure that the allocation of any Federal
Department of Education funds is subject to rigorous compliance with
Federal law and Administration policy, including the requirement that
any program or activity receiving Federal assistance terminate illegal
discrimination obscured under the label “diversity, equity, and
inclusion” or similar terms and programs promoting gender ideology.
Sec. 3. General Provisions. (a) Nothing in this order shall be
construed to impair or otherwise affect:
(i) the authority granted by law to an executive department or
agency, or the head thereof; or
(ii) the functions of the Director of the Office of Management and
Budget relating to budgetary, administrative, or legislative
proposals.
(b) This order shall be implemented consistent with applicable law
and subject to the availability of appropriations.
(c) This order is not intended to, and does not, create any right or
benefit, substantive or procedural, enforceable at law or in equity by
any party against the United States, its departments, agencies, or
entities, its officers, employees, or agents, or any other person.
DONALD J. TRUMP
THE WHITE HOUSE,
March 20, 2025.
Why do Republicans want to abolish the Department of Education?
Why is closing the Department of Education . . . expected to improve
the quality of the school system in the USA?
There is no legitimate reason to think that it will, and improving the quality of the school systems in the U.S. isn't a significant motivation for doing so.
Even Section 1 of the Executive Order, which observes that the Department of Education manages to administer its student loan portfolio with less than 0.1% of the personnel of commercial banks engaged in similar activity, seems to refute any claim that the Department of Education is inefficient or wasteful.
Section 2(b) of the Executive Order, similarly, actually calls for unprecedented centralization of authority over educational policies in the federal government, rather than restoring authority to state and local governments, exactly contrary to the alleged justification for the EO in its title, its rhetoric in Section 1, and the related press release from the White House. There is no statutory authority for this part of the Executive Order, which would seem to be facially invalid as a result.
Many Republicans don't support public education in general
Many Republicans have a low opinion of the value of public education and of higher education as a whole, often believing that it does more harm than good, so from that perspective, eliminating federal support to educational institutions (many of which are private rather than state supported), is a good thing, because it undermines higher education.

(Source)
But a March 2025 poll suggests that these views have evolved:
The survey of 500 Republican voters found that most respondents, 63
percent, view four-year degrees as valuable—including 60 percent of
voters who have “very favorable” perceptions of President Trump. Trade
schools and community colleges enjoy particularly robust support; 91
percent and 87 percent of respondents, respectively, view them
favorably. By comparison, 69 percent hold favorable views of four-year
colleges and universities, and 37 percent feel positively toward
for-profit universities.
At the same time, Republicans surveyed believe the most needed reforms
in higher ed today are greater accountability and greater
affordability.
Most respondents, 87 percent, support increased accountability for
higher education institutions. And many believe the government should
play various roles to ensure that principle is upheld. Seventy-one
percent agree that the federal government should require transparency
from institutions and accredit them based on their value to students.
The same share believe there should be federal guardrails to prevent
“bad actors” from charging students for low-quality degrees. And
nearly half agree taxpayer dollars should be withheld from colleges
that don’t offer a sufficient return on students’ investment.
Toward that end, 83 percent of Republicans support the financial value
transparency rule, which requires colleges to report program-level
information like the total cost of attendance and the amount of
private education loans disbursed to students. To make college more
affordable, 81 percent of Republicans are in favor of Pell Grants,
federal financial aid for low-income students, and 79 percent support
the Public Service Loan Forgiveness program and income-driven
repayment for student loans. Almost 70 percent favor borrower defense
to repayment, allowing students who attended fraudulent institutions
to have their student loans discharged.
Of course, as always, public opinion is often malleable and inconsistent, and polling often produces inconsistent results depending upon the way that questions are asked.
Key Republican officials favor factually false curriculums
Much of the Republican base believes things about history and science (and other topics) which are factually untrue and want to inject that into the curriculum, which would be easier without any federal involvement in education.
Many key Republican officials would also like to inject false, and racially discriminatory, elements into K-12 curricula, and removing federal government civil rights authority over educational institutions could make it easier for state and local governments to do that in public schools.
For example, Republican elected officials in Oklahoma want to require that students be taught that there was significant fraud in the 2020 election, as President Trump falsely claimed in litigation the resulted in many of his attorneys being sanctioned or disbarred.
Similarly, Republicans in Florida in 2023 set curriculum standards that teach students that Black people benefited from slavery.
Many Republicans have also long sought to remove science instruction that conflicts with religious doctrine, like the teaching of evolution in schools.
President Trump pushed the 1776 Project in his first term, "to support what he called "patriotic education". The commission released ;The 1776 Report' on January 18, 2021, two days before the end of Trump's term of office. Historians overwhelmingly criticized the report, saying it was; filled with errors and partisan politics'".
Trump actions in his second term have sought to federalize authority of education, not to return it to the states
President Trump, so far in his term, despite his rhetoric regarding returning authority over education to the states, has actively pushed to investigate and withdraw federal funds from both K-12 educational institutions, and from higher education, when those institutions are managed in a manner that disagrees with his views, exactly contrary to the notion of abdicating federal authority over education. This has, for example, caused an Idaho school district to order a teacher to remove an "Everyone is Welcome Here" poster for fear that it would violate President Trump's Anti-DEI Executive Orders, even though the district is not part of the federal government and only receives federal funding (like every other public school district).
Arguably, these are tactical moves intended to build liberal political support for removing federal involvement in schools, but there is no publicly available affirmative evidence that this is Trump's plan.
Federalism arguments
A minority of Republicans are genuinely interested in shifting the duty of raising and distributing funds administered by the Department of Education from the federal government to state and local governments, thereby reducing federal spending and increasing state and local government spending, either because they think that this reflects the original intent of the Founders in our federal system under the U.S. Constitution, or because they trust their own state and local governments more than the federal government in a general, non-specific way.
But federalism considerations are rarely a hot button issue for anyone. This argument doesn't have much political heft outside of conservative think tanks.
Furthermore, any effort to shift education related programs from the federal government to state governments requires the involvement of state and local governments in lengthy consultations with them, in order to avoid harm to students. It can't just be done unilaterally in an Executive Order. The approach taken in this Executive Order is not consistent which a sincere and legitimate desire to disentangle the federal government from involvement in education in a way that does not harm students or reduce the quality of education in the United States.
