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. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=8a9a3970-e486-43f5-8aed-116aa1d919df&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional) ## Video: President Trump Signs The GOP Tax Bill Into Law [Watch (HLS stream): President Trump Signs The GOP Tax Bill Into Law](https://cdn.jwplayer.com/manifests/3iWi0gjT.m3u8) (2:02)  _Published 2017-12-22. President Donald Trump has signed into law a $1.5 trillion tax overhaul package._  by [John Patrick Pullen](https://time.com/author/john-patrick-pullen/)  ## John Patrick Pullen Dec 28, 2017 1:09 AM UTC  'For Sale' sign in front of house (focus on sign) 'For Sale' sign in front of house (focus on sign)Thomas Northcut—Getty Images  by [John Patrick Pullen](https://time.com/author/john-patrick-pullen/)  ## John Patrick Pullen Dec 28, 2017 1:09 AM UTC A last-minute announcement by the IRS could hurt many taxpayers rushing to prepay their 2018 property taxes before the end of the year. Late Wednesday, the IRS announced that filers could [claim their 2018 property tax payments](https://www.irs.gov/newsroom/irs-advisory-prepaid-real-property-taxes-may-be-deductible-in-2017-if-assessed-and-paid-in-2017) on their 2017 federal taxes only if the taxes had been assessed in 2017. The news, with just two business days left before the end of the year, spreads even more confusion among millions of taxpayers across the country who are hoping to take one last big property tax deduction before the GOP tax plan takes effect on Jan. 1. With filers across the country asking “Should I prepay my 2018 property taxes?” the federal government’s announcement Wednesday has whipped state and local tax collectors into a frenzy as they try to determine if early payments for 2018 property taxes will let their local citizens take an extra-large deduction on their federal taxes in 2017. And the news is not good for everyone. As a part of the Tax Cuts and Jobs Act, which [President Trump signed into law](http://time.com/5077411/donald-trump-signs-tax-bill/) last week, a new $10,000 limit on deductions for state and local taxes will take effect in 2018\. That $10,000 limit combines both local property and income taxes, and could mean taxpayers in states like New York, Illinois and California who pay higher local taxes could take a big financial hit. It was widely believed that one way ease the pain — for next year, at least — would be for filers to prepay their 2018 property taxes before 2017 ends. But the IRS advisory clarified the federal rules Wednesday afternoon. The new guidance states that prepayments are only tax-deductible “under certain circumstances”: --- > “” --- The final word by the federal government has created confusion among taxpayers and collectors alike. Just days prior, New York Gov. Andrew Cuomo [issued an emergency executive order](https://www.governor.ny.gov/news/governor-cuomo-takes-emergency-executive-action-deliver-property-tax-deductibility-new-yorkers) authorizing the collection of early tax payments, a proclamation rendered moot if the IRS won’t ultimately honor the deductions on 2017 federal tax returns. > [](https://twitter.com/NYGovCuomo/status/946066795357650944) Meanwhile, Long Island property owners have nothing to fear, reports _Newsday_, because Nassau and Suffolk counties — like many other areas across the country — have already sent out bills based on the assessed (not estimated) values. > [](https://twitter.com/RachelleBlidner/status/946149069478612997) In contrast, [Westchester County officials](https://www.wsj.com/articles/irs-2018-property-taxes-have-to-be-assessed-to-qualify-for-prepayment-1514417581) said that they would not be able to crunch the numbers for their property owners in time, according to the _Wall Street Journal._ On the west coast, some local governments are shooing away taxpayers by not even allowing pre-payments at this time. Los Angeles County is not allowing pre-payment of 2018-2019 tax bills because the tax bills will not be generated until September 2018, at the earliest, the county assessor’s office said [in a statement](http://www.lacountypropertytax.com/portal/pdf/JointStatement2017.pdf). Likewise, San Francisco county is not allowing pre-payment, and did not provide a date for when they would do so.
