"ECOS, a consulting firm led by Sylvestre, demonstrated excellent skills in planning, organizing, and managing the evaluation process of a project on poverty reduction and empowerment for women in women-headed households in Rwanda. The team delivered a high-quality evaluation report that met our expectations and provided valuable insights and lessons for our future work. I highly recommend ECOS to other organizations looking for reliable and competent evaluation consultants."

""I would like to thank ECOS on behalf of our entire team for the great work and the excellent report. It gives us very valuable indications and orientation on what still needs to be done to improve the TVETs in terms of gender equality"."

"Minority Rights Group International (MRG) and Rwandan based organizations, African Initiative for Mankind Progress Organization (AIMPO) and Women’s Organization for Promoting Unity (WOPU), implemented a three-year project (June 2018-June 2021) entitled “Strengthening the capacity of CSOs, HRDs, and Media Houses to challenge discrimination against Historically Marginalized People (HMP) and promote their rights in Rwanda” that was financed by European Union. At the completion of the project, MRG contracted Educational Consulting Success (ECOS Ltd), represented by Mr. Musengimana Sylvestre, to conduct a final external evaluation of this project. ECOS Ltd carried out the evaluation from July 2021 to October 2021.
We are hereby confirming that ECOS Ltd completed the evaluation to a high standard and within the required time frame and we would recommend ECOS Ltd to other organizations for similar assignments. Should anyone need more information about ECOS Ltd, they should feel free to contact us."

"We take the opportunity to thank you and your team at ECOS for an excellent work throughout this year to conduct the qualitative study on stunting prevention and reduction. Despite external inconveniences the world has experienced, you have always delivered in a timely manner and we appreciate that a lot. We hope these findings are useful for NCDA."

"Sylvestre was a valued member of our team evaluating UNHCR’s approach to learning and development during 2020. Sylvestre undertook two country case studies (Djibouti and Morocco) as the sole researcher, interviewing the workforce and partner staff. His fluency in French and English and his excellent interviewing, evaluation, and writing skills produced thorough and well-organized interview summaries (in English) that were a valuable contribution to the team’s overall findings. Sylvestre presented the results of his findings in feedback sessions for senior staff in the two country offices and then supported the team in presentations of the preliminary overall findings to HQ staff. Sylvestre also made valuable contributions to team discussions on methodological approaches and techniques drawing on his extensive experience and training. His solid, professional approach and his warm and constructive personality made him a pleasure to work with. I would strongly recommend him as an evaluation consultant and team member."

"I feel privileged to work with Sylvestre, who coordinated all the logistics for an evaluation in Rwanda. He is of sterling character, and worked tirelessly on the very complex assignment we had. Sylvestre is committed to excellence, and went beyond the call of duty to ensure that we delivered a high quality product of our evaluation - and on time. He possesses great diplomatic skills, and fielded requests from all members of our team professionally, as well as efficiently. An excellent organizer with great attention to detail, I would not hesitate to recommend him for similar assignments."

"Sylvestre was an integral part of the Team that conducted the Mid-Term Performance Evaluation of the USAID/Rwanda Strengthening the Capacity of the Health Sector to Deliver Quality Health Services (SCHS) Project. He was a unique member of the team who played a duel role – both as the main Logistics Coordinator and a supporting Evaluator/Analyst. He is a thoughtful detail oriented, but results focused individual. His superb interpersonal and communication skills, along with deep knowledge of the local context and people, made him an indispensable resource for the team. He masterfully coordinated the logistics for all the meetings and site visits that the team had to conduct, mostly under very complex circumstances and timeframe. In addition, he was also part of a sub-team where he very impressively and competently contributed to the analytical part of the evaluation work. All in all, Sylvestre performed as a very hardworking, proactive, and a dynamic professional with a very positive attitude. During our assignment, he routinely went beyond the call of duty to effectively help advance the work and goal of the team, even at times working after hours and holidays. It was an absolute pleasure and honor for me to work with such a fine professional – I would recommend Sylvestre in the highest possible terms!"

"Sylvestre was an excellent research partner in Rwanda. He has an excellent understanding of local context, he is well connected and organised. His command of English is super. Sylvester helped as a research partner to set up interviews, to conduct fieldwork, to translate during interviews and focus groups and to identify key lessons arising out of the field. He was even willing to play games with the children. It was really a pleasure"

"It is my pleasure to write a brief recommendation for Sylvestre Musengimana. He is an experience development consultant and an expert workshop facilitator. I have had the opportunity to work together with Sylvestre on two consultancy projects. When I think back on these experiences of working with him one word comes to mind “Professional.” He goes above and beyond to ensure a project runs according to plan and that the final product meets or exceeds the client’s expectations. I recommend Sylvestre without any reservations and hope that I have a chance to work with him in the future"

"I have worked with Sylvestre as consultant for the last five years. Sylvestre is result-oriented personality with eyes to details. His people management is excellent"
