Hi Antonella, glad you are looking into Esri technical certification! It is a great thing to add to your resume and to grow your professional ArcGIS skills. Esri has some brand-new certifications releasing in December (and more coming in early 2022) that may pique your interest. Depending on your level of experience with ArcGIS Pro, you may consider taking the ArcGIS Pro Foundation exam (more entry-level) or the ArcGIS Pro Associate exam (multiple years of experience--most likely the exam for you).
Once you go to the exam page, you can click the Download Exam Information button to learn more. The ArcGIS Pro exams will be publicly available in mid-December, and at that time, the last page in the Exam Information Guide will have a learning plan full of courses we recommend you take to prepare for the exam.
There is also a GIS Fundamentals exam coming in 2022 that is for those who can perform entry-level mapping and visualization tasks, sharing, and analysis.
This Preparing for Esri Technical Certification web course may also be helpful. Let me know if you have any follow-up questions.
