### 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.

Monday is [Martin Luther King, Jr. Day](http://time.com/3661538/mlk-day-reagan-history/), and it means more than just the closure of government offices. Here’s what you need to know about the holiday.

The day celebrates the birthday of Martin Luther King, Jr., which is Jan. 15\. The holiday is observed on the third Monday of January.

King was assassinated in 1968, but it wasn’t until 1983 during the Reagan administration that the holiday was established. President Reagan was initially hesitant to designate the holiday, but, [as TIME reported](http://time.com/vault/issue/1983-08-15/page/12/) at the time, “Faced with inevitable congressional passage of a bill to make Martin Luther King‘s birthday a national holiday, Reagan swallowed his longstanding objections that this would open the door to many other groups seeking similar holidays and decided that he would support the measure.”

After the bill passed in 1983, the holiday started being officially observed in 1986\. As TIME’s Lily Rothman [explains](http://time.com/3661538/mlk-day-reagan-history/), having one’s birthday as a national holiday was an honor that at that time had only belonged to George Washington.

As the holiday is celebrated, Clayborne Carson, founding director of the King Institute, professor of history at Stanford University and author of _Martin’s Dream_, has some suggestions about how parents should teach their children about King. “If you put someone on a pedestal, they you can’t really be like them,” Carson [told TIME](http://time.com/3673613/how-to-talk-to-your-kids-about-martin-luther-king-any-day-of-the-year/). “But if you realize that he was a human being just like the rest of us, who was caught up in a great movement and did extraordinary things, then people begin to understand that they can do extraordinary things, too.”


## Transcript

>> I grew up hearing Dr. King. There was something about his voice, maybe about his appeal.

>> Dr. King had collected a lot of social themes, and couplets, and words, and language. And he brought all the best of those years of speaking together in one gloriously magnificent knowing.

>> I have a dream--

>> When he spoke that day on the steps of the Lincoln Memorial, he was preaching from his heart, from his soul, from his guts.

>> As the day of the march drew near, I stayed at the Willard Hotel where Dr. King was staying. Now, among his advisers, there were those who were suggesting, " Martin, people are coming to the march in Washington because they're coming to hear you preach and there were others "-- And he said, " No, Dr. King, we have to give the kind of political direction that treats us to where we are. I was part of that group. And he was being very gracious. He said, " Well, thank you so much, but I'm gonna go up and work in speech and counsel with the Lord ."

>> At the day of the speech, I'm standing on the platform about 50 feet behind him.

>> I had no credentials, but I kind of crawled up the steps and backed my way in.

>> Everybody was curious as to what this young man is going to say. As you would expect, We have large crowd like that. people had their own mini conversations going on, you know.

>> But when Dr. King got up, it got quiet. I mean, it was like they were at church. [ unk ] A. Philip Randolph in this enormous voice.

>> I have the pleasure to present to you, Dr. Martin Luther King, Jr.

>> I couldn't get to him to wink my eye or to say to him like come on, come on, you can do it, you can do it.

>> And after a couple of perfunctory introductory senses, I'm listening to his--

>> Five score years ago--

>> I concentrated on his words and what he was saying. As I'm listening, I see that he is reading. I had written out in longhand a possible opening paragraph.

>> America has given the Negro people a bad check.

>> And I did notice at a certain point he starts off reading. And at a certain moment, Mahalia Jackson, it erupted to him while he's speaking. Tell them about the dream, Martin. Tell them about the dream. His whole body language changed and he changed to what I call the baptist preacher's stance. And I said to the person standing next to me, whoever that was, I said, " These people don't know it, but they're about ready to go to church ."

>> I have a dream that one day--

>> Yes!

>> this nation will rise up.

>> Like the greatest jazz musician, he just does an incredible solo. It was as if some transcendental terrestrial force had come down and taken over his body.

>> I didn't know that Dr. King had left a script, but that's what was in there.

>> And you stood in wonder as he spoke, as his words came out.

>> My 4 little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character. I have a dream today--

>> When-- In his talking and my mind wandering back to what I had been through and when he started talking about his children, you know, I felt like, wow, he's talking about me.

>> You know it by then Dr. King is a musician. And if he was reciting a telephone book, the rhythms and transition to phrasing, you know, would be-- would bring you to an emotional acceptance.

>> And once in southwest Georgia, he heard people signing a song about over my head I can see freedom in the air. And I think all of it just saw the King together. With this faith, we will be able to transform the jangling discords of our nation.

>> We live in realities lots of times and somebody talks about the dream, you know, you get a certain image, but the image that he gave was a future. And it wasn't beyond our reality to think that certain things could happen.

>> We were looking for leadership and he was offering it. The I have a Dream speech was a summon, a call to the collective conscience of America that we can be better than this.

>> Free at last!

>> Yes.
