Before we can discuss Project Management Course, Project Management Certification, or Project Management Training Programs available in the market, we must first understand the basics.
Project Management is a field or domain. One must first understand the basics of the subject before making a decision about whether one should be an expert in any of its aspects. Many misconceptions and incorrect assumptions about project management can prevent it from being fully utilized.
These misconceptions will be dispelled by the following points:
Project Management is not industry or domain specific.
Project Management is a valuable life skill
Project Management can be a career in itself
Project Management concepts can be successfully applied beyond projects
Project Management is not only for experienced professionals.
It is a broad field with many courses and certifications. There are professional certification courses and degree/diploma courses offered by many recognized institutions.
Project Management Institute (PMI), one of the most recognizable institutions, offers a variety of certification courses in Project Management.
Here are a few examples:
PMI-CAPM Certified Associate in Project Management
PMI-PMP Project Management Professional
PMI-PgMP Professional in Program Management
PMI-PfMP: Portfolio Management Professional
PMI-ACP: Agile Certified Professional
Schedule Professional
PMI-RMP: Risk Management Professional
DASM/ DASSM = Disciplined A Scrum Master/ Disciplined Senior Scrum Master
DAVSC: Disciplined Agile Stream Coach

Similar to Axelos, many MBA Schools, Agile Framework based institutions, and many more, there are many other institutes. There are 250+ Agile Certifications available on the market.
Although the process for getting certified may vary depending on the certification, it is the same. You must attend a training session to understand the next steps, submit a request and get it approved. Next, you will need to prepare for the exam by taking mock exams, reviewing your scores, improving your score, and finally clearing the exam. Based on the certification chosen, an application process may be required.
This requires professional counselling to determine which course is right for you and which could help you grow in your career.
Each course is unique, but the outcome or deliverable from each one is the same: Knowledge Gain. This one output can lead to many other related or secondary outputs.
These courses in project management will teach you the following topics:
Tools and Techniques to successfully manage and deliver your project
Compliance and Ethics
Standards and Regulations
Policies & Procedures
Options for customizing and tailoring standards
Do’s and Don’ts
Benchmarks

These skills are just a few of the many other important ones that you can learn.
How to improve your interpersonal skills
How to develop leadership qualities
Analytical Skills: How to analyse problems
How to solve problems (Problem Solving Skills).
Many life skills are applicable beyond projects

These points are taught in the courses. However, it is important to apply them in practice. Failures are not the way to go. Learning from your mistakes is the only way for you to succeed. It is important that everyone who has completed these courses applies the learnings in real-life situations and moves through the Shu Ha-Ri stages.
The final deliverables for an individual are:
The primary output of any course or certification is the knowledge gained by an individual. How well this is done will determine the quality of all other outputs.
Credibility in the marketplace and within the organization: A certified person always carries a credibility that can be relied on for information. The individual is responsible for maintaining that credibility after he/she has completed the course/certification.
Performance improvement: A certified individual must apply the knowledge and produce results. This is the expected output and if it is not delivered, it will impact credibility. Performance of an individual is expected to improve post completion of the course/certification.
Thinking outside the box: With a variety of tools and techniques learned and the additional information gained, one is expected to think differently and try out different methods that might lead to better results.
Clarity of thought and approach: Individuals are expected to use the knowledge they have gained to make informed decisions and to help others. A certified individual should be able to think SMART. (SMART: S- Specific, Measurable M- Acchievable A – Achievable R – Realistic T-Time Bound
