Despite medical and technological advances, half of the world’s population lacks access to essential health services, and over 8.9 million preventable deaths occur every year. There is an acute global shortage of health workers, a gap that will grow to 18 million by 2030. Studies show that training high-performing community health workers can help close these gaps and save more than 3 million lives annually. In the past few decades, many community health worker programs across the world have demonstrated their ability to save lives — including in the hardest-to-reach areas. Yet despite this progress, lessons on how to successfully scale these programs as part of national primary health systems are not widely shared. This course, developed in collaboration with the Community Health Academy at Last Mile Health, introduces learners to the core concepts of community health worker programs, and explores what is needed to build and strengthen large-scale programs in order to improve access to high-quality health services. The curriculum highlights the key components of designing community health systems, addresses common management challenges, and showcases lessons learned from a range of contributors — from community-level practitioners to government leaders and other global health experts. Through case studies of exemplar countries (including Ethiopia, Bangladesh, and Liberia), participants will learn from leaders across the globe how to advocate for, build, and optimize community health worker programs. This course was created by health systems leaders for health systems leaders. Whether you work in a Ministry of Health, lead or support a community health worker program, mobilize resources and advocate for increased investment in community health, or you are simply interested in knowing what it takes to deliver quality care through community health worker programs, learners will have the opportunity to advance their knowledge and skills to implement critical change. This course can be taken individually, but learners are also encouraged to convene their colleagues from within or across organizations to share insights and further enhance the learning experience. About the Community Health Academy Last Mile Health launched the Community Health Academy in 2017 to revolutionize training for community health workers and health systems leaders. The Academy is equipping current and next-generation health systems leaders to build strong community health systems through university-quality courses that are delivered virtually and in-person through coaching, mentorship, and group discussion. The Academy is also supporting Ministries of Health to enhance the effectiveness of their health worker training by deploying mobile phones equipped with high-quality digital content to frontline and community health workers.

How to distinguish employees from independent contractors. What you'll learn: Learn common factors used to test whether a worker is an employee or independent contractor Apply common factors to their personal business situationUse Self-Assessment Tools to identify business practice that may adjustment so workers can be properly classified as independent contractorsKeep organized records of your contractors' classifications Understanding Worker Classification is a crash course that will help business owners learn the factors used to determine whether a worker is an employee or independent contractor. The additional bonus resources included with the course are:Independent Contractor v. Employee Self-Assessment questionnaire (one for each test covered in the course: 20 factor, IRS Test and Economic Realities Test);Independent Contractor Worksheet (one for each test covered in the course: 20 factor, IRS Test and Economic Realities Test); 5 Step Guide to Conducting your Self-Audit; 20 Factor Cheat Sheet with examples; 50 State Survey that sets forth the worker classification tests used in each state; and IRS Independent Contractor Information Sheet Form Independent Contractor Agreements for Single Projects and Recurring ProjectsThere is about 2 hours of learning material including videos, power point presentation, and audio recordings. I will discuss some background issues on worker classification and then dive right into the 20 factor test. I will define each factor and discuss a comparison of two cases: one where the worker was determined to be an independent contractor and another where a class of workers were found to be employees. That way, you can see real situations that these factors were applied and learn common "do's and don'ts." After every 5 factors, I will do a brief recap and discuss important take-a-ways. Once we conclude the 20 factor test, I also address the IRS Test and the Department of Labor Economic Realities test. I will then go through next steps for your business and the 5 simple steps to conduct your self-assessment. After that, I do a lecture where I discuss the key provisions of the form contracts that are included in the course and then I give a course wrap up. Worker classification is a hot issue for the federal government and state agencies which have increased audits in this area. Understanding these issues will help your business get proactive and hopefully stop a problem before it starts. Please remember that the information in this course should be used as a general reference and you should not solely rely on this information for making legal decisions. You should consult an attorney for employment law issues.
