Courses available on SL-Institute

SL-Institute offers two types of courses.

1. Online courses built on the smart learning platform. They include lessons, modules, quizzes, audios and videos. This content is available 24 hours a day, 7 days a week on the platform.

To complete a course, you must complete all chapters and pass all exercises, which include quizzes and activities. If you do not, your progress bar will not indicate that you have completed the course and, for those who qualify, you will not be able to access the certificate. Use the progress bar to check the status of each quiz and activity to make sure they are complete. If you have checked all the exercises and your progress remains incomplete, there may be a technical problem. Contact us by clicking on "Contact Us" and include in your request the name of the course, add a link to the course, include a screenshot, the name of the browser and the name of your operating system, etc. Our technical team will investigate the problem.

2. Electronic books (e-books) are available by digital download.

These courses introduce the different concepts and allow you to learn on your device, at your own pace. You don't need to log in to the platform every time you want to work through the courses. Some exercises are available on the eBooks for you to practice.

Report a typo or error in a course
Our training teams are constantly working to ensure the quality and currency of our courses, but errors can slip through the cracks. If you encounter an error on a course, please feel free to notify our team by clicking the "Contact Us" button located at the bottom of the page in the footer. If possible, please include a screenshot and any additional details.
What if the videos or images are not available?
Below are several troubleshooting options for you to consider:
- Check for extensions (plug-ins) installed on your browsers, such as AdBlock, which can block images and videos.
- Change browsers or disable some extensions; you should be able to watch our videos without any problems.

If you are still unable to access, it may also be due to a security system set up on your network, especially in a professional environment, with a restrictive firewall.
- If you are not on a home network, ask the administrator if they can change your access permissions.
- If you are on a home network, add as an authorized site to see if that solves the problem.
