### FAQ

#### Is a PMP certification worth it?

A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations.

#### What are the best certifications for project managers?

The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation.

#### How does PMI support career growth for professionals?

PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers.

#### What is the PMBOK® Guide?

The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery.

#### How is AI changing project management?

AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment.  PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes.

#### What are the most important skills for a project manager?

Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates.


#### How can I get involved with the PMI community?

Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections.

#### What is the difference between PMP and CAPM?

The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification.

#### How does PMI support social impact?
PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

President Donald Trump [signed](https://www.youtube.com/watch?v=C%5FY-udVHdb4) two proclamations Monday, dramatically reducing the size of two [national monuments](https://time.com/4925184/us-attractions-visit/) in Utah and reviving a long-running legal dispute over the limits of presidential authority under the Antiquities Act of 1906.

The [proclamations](https://www.whitehouse.gov/presidential-actions/proclamations/) reduced by 90% the protected areas of Bears Ears and the Grand Staircase-Escalante. 

Bears Ears is a pair of symmetrical buttes that dominate the horizon in southeast Utah. The monument spanned some 1.36 million acres before Trump reduced it to 131,100\. The Grand Staircase-Escalante is a set of step-like sedimentary layers that connect to the rim of the Grand Canyon. Trump reduced the monument from some 1.87 million acres to 181,500\. 

Together, the two presidential proclamations could open up more than 3 million acres of formerly protected land—including sacred tribal sites—to exploration for oil, minerals, and gas, as well as motorist and non-motorist recreation.

Preservation advocates and tribal representatives have criticized the changes, while suggesting that greater cooperation between the federal government and tribal leadership is required.

The Bears Ears Inter-Tribal Coalition—which includes the Hopi Tribe, Navajo Nation, Ute Mountain Ute Tribe, Pueblo of Zuni, and Ute Indian Tribe—said that the sites contain “thousands of sacred cultural sites and important areas of spiritual significance.” 

In a [press release](https://www.prnewswire.com/news-releases/tribal-nations-reaffirm-commitment-to-bears-ears-following-monument-rollbacks-302825609.html) shared Tuesday, the coalition wrote, "Tribal Nations understand Bears Ears as an interconnected living cultural landscape, where the land itself—and the relationships among its cultural sites, waters, plants, animals, and sacred places—are what must be protected."

The coalition originally advocated for the designation of national monument status, which was granted by President Barack Obama in 2016\. It then [sued](https://www.narf.org/nill/documents/20191107bearsears-amended-complaint.pdf) the Trump Administration in 2017 for attempting to resize the monument, though the case was suspended when President Joe Biden restored its original boundaries in 2021—and expanded the site by 12,000 additional acres. 

The coalition has since said that the governments it represents, going forward, require “a meaningful voice in the development of a land management plan” for Bears Ears.

“President Trump’s outrageous attack on Grand Staircase-Escalante and Bears Ears national monument was taken at the urging of Utah politicians,” Scott Braden, the Executive Director for the Southern Utah Wilderness Alliance (SUWA), [said in a statement](https://suwa.org/suwa-statement-on-trumps-illegal-reductions-of-grand-staircase-escalante-bears-ears-national-monuments-7-13-26/). “These two landscapes deserve to be protected for current and future generations of Utahns and Americans, not opened to exploitation.” 


The SUWA expressed plans to contest the proclamations in court.

The Wilderness Society also criticized the proclamations, accusing the administration of ignoring "the voices of Tribal Nations, local communities, and the millions of Americans who want these places protected for future generations,” according to a [statement](https://www.wilderness.org/articles/press-release/president-trump-virtually-eliminates-bears-ears-and-grand-staircase-escalante-national-monuments#) from its president, Tracy Stone-Manning, who was the Director of the Bureau of Land Management under Biden.

Utah politicians, however, expressed support for the measures, which returns the affected lands to their prior federal management status. 

“For too long, presidents have weaponized monument designations to lock up millions of acres, close roads, restrict grazing, and cut rural communities off from lands their families have lived on and worked for generations,” Republican Sen. Mike Lee said in a statement on Monday. 


Republican Governor Spencer Cox, who was present at the White House when the proclamations were signed, wrote [on X](https://x.com/GovCox/status/2076804244267810919) that “the question has never been whether to protect Bears Ears and Grand Staircase-Escalante national monuments, but how to protect them best.”

He continued: “We deeply value these natural, cultural, and scientific treasures. The historic landmarks and other nationally significant resources remain under federal protection, while allowing agencies to direct limited resources toward caring for these specific sites rather than millions of surrounding acres.”

Trump’s proclamations challenge the limits of presidential authority when it comes to managing public lands, with implications that extend far beyond Utah. At the heart of the debate is the [Antiquities Act of 1906](https://www.nps.gov/articles/lee-story-appa.htm).

## What Is the Antiquities Act?

Unlike national parks, whose designations must be approved by Congress, national monuments are given that status by the sitting president under the Antiquities Act. It was signed into law by President Theodore Roosevelt in 1906\. 


The Congressional Research Service (CRS) [said](https://www.congress.gov/crs-product/R41330) ​​that the Antiquities Act has been used by 18 U.S. Presidents to establish 168 protected areas, including marine monuments. President Bill Clinton established Grand Staircase-Escalante in 1996, two decades before Obama [established](https://obamawhitehouse.archives.gov/the-press-office/2016/12/28/proclamation-establishment-bears-ears-national-monument) Bears Ears. 

While presidents have frequently used the Act to enlarge existing monuments, Trump is the first President since John F. Kennedy to reduce the scale of a monument. Several earlier presidents—including William Howard Taft, Woodrow Wilson, Calvin Coolidge, Franklin Delano Roosevelt, Harry S. Truman, Dwight D. Eisenhower, and John F. Kennedy—also reduced monument boundaries. However, Trump's reductions are unprecedented in scale and may therefore face greater legal scrutiny.

The legal debate centers on the fact that while the Antiquities Act expressly authorizes presidents to establish national monuments, it does not explicitly address whether later presidents may shrink or abolish them. 


“My position has long been that the president does not have that authority,” Mark Squillace, professor of law at the University of Colorado Law School, tells TIME. “If you read the statute, the Antiquities Act, it specifically gives the president the authority to reserve monuments that contain historic objects and of scientific interest, but it does not give the president the authority to modify or revoke monuments that have been declared by prior presidents.”

He says that it’s important to look at the exact wording included in the text, because there are contemporaneous laws that specifically give the president those kinds of authority—for example, the 1897 Organic Administration Act's [amendment](https://www.ntc.blm.gov/krc/system/files?file=legacy/uploads/23148/Organic%20Administration%20Act%20of%201897.pdf) to the Forest Reserve Act, which expressly says the President may "revoke, modify, or suspend" national forest proclamations and "reduce the area or change the boundary lines."

“So the argument is simply that when Congress wants to give the president broader authority, it has specifically done so,” Squillace says. 


The Act’s exact language has been carefully scrutinized over the years. Of particular note is the line that says national monuments must be limited to the “[smallest area compatible](https://www.nps.gov/articles/lee-story-appa.htm) with proper care and management of the objects to be protected.”

The Trump Administration alleges that both Clinton and Biden sought to protect a sweeping landscape that overly broadened the scope of the legislation as it is written.

“Where the President determines that the structures and objects identified by a prior monument proclamation no longer are, or never were, deserving of the Antiquities Act’s protections, the Antiquities Act permits the President to remove land from the monument and return it to its prior federally managed status,” Trump wrote in a [proclamation](https://www.whitehouse.gov/presidential-actions/2026/07/modifying-the-bears-ears-national-monument/) on Monday.

He also wrote that the previously established Bears Ears National Monument “suffers from several flaws under Antiquities Act analysis” and that “generic” features “are not historic landmarks, historic or prehistoric structures, or other objects of historic or scientific interest.” The proclamation also argues that the Bears Ears region “contains several resources that are vital to energy and resource independence and, in turn, critical to national security.” 


Similarly, a [proclamation](https://www.whitehouse.gov/presidential-actions/2026/07/modifying-the-grand-staircase-escalante-national-monument/) for the Grand Staircase-Escalante says that the region contains resources that are “essential to important sectors of the economy of the United States, including defense, manufacturing, and transportation.” It also says that most of the areas around the monument are “already adequately protected by Federal law and do not require a reservation of land under the Antiquities Act for protection.”

Historically, courts have upheld broad presidential authority to grant monument status under the Antiquities Act, but they have not definitively ruled on a President’s power to revoke or reduce that designation.

Were it to advance through the courts, however, Squillace believes that the text of the statute would stand on its own. “This particular Supreme Court has been very narrow in its interpretations about delegations of power, and has made clear that the authority to delegate power is limited by the specific text of the law,” he says. 


In its assessment, the CRS said, “Given the recurring controversies over presidential monument proclamations, Congress continues to evaluate whether to abolish, limit, or retain the President's authority under the Antiquities Act.” It does not go into further detail about what those assessments would entail or provide a timeline. 

However, “a few years ago Congress [passed a law](https://www.congress.gov/bill/111th-congress/house-bill/146), which basically acknowledged the existence of the Grand Staircase Escalante National Monument,” Squillace says, explaining that it basically confirmed the existence of the monument as it stood at the time. “Utah's made hundreds of millions of dollars on the lands that they got in exchange for giving up lands within the Grand Staircase Escalante National Monument … so that's going to be a really tough one for the court to reverse.”

“But I certainly think that you're likely to see litigation sooner rather than later over these decisions,” he says.

The proclamations will go into effect in 60 days.
