A current status guide for MLS-C01, including the March 31, 2026 final exam date, three-year certification validity for existing holders, historical exam format, former domain weights, and current AWS AI/ML certification planning options.
MLS-C01 should no longer be treated as an active exam after March 31, 2026. Candidates planning a current AWS AI/ML credential should review active AWS paths rather than building a new Specialty exam plan.
Use these points before planning around the retired AWS Machine Learning Specialty exam.
AWS Certified Machine Learning - Specialty (MLS-C01) is retired as of the current update date.
AWS listed March 31, 2026 as the last day to take the MLS-C01 exam.
AWS stated that certification holders keep an active certification for three years from the date the credential was earned.
The exam guide listed 65 multiple-choice or multiple-response questions in a 180-minute appointment.
AWS reported scores from 100 to 1000, with 750 as the minimum passing score for MLS-C01.
Review active AWS AI/ML credentials such as AI Practitioner, Machine Learning Engineer - Associate, and Generative AI Developer - Professional.
AWS stated that Machine Learning - Specialty was being retired and that March 31, 2026 was the last day to take the exam. After that date, MLS-C01 should be handled as a retired credential.
Because the exam is retired, candidates should not build a current study plan around scheduling MLS-C01. Any page or provider still presenting it as active should be checked against AWS Certification before relying on it.
MLS-C01 historically validated the ability to design, build, deploy, optimize, train, tune, and maintain machine learning solutions on AWS. Its domains covered Data Engineering, Exploratory Data Analysis, Modeling, and Machine Learning Implementation and Operations.
Candidates should now compare active AWS credentials by role: AI Practitioner for broad AI literacy, Machine Learning Engineer - Associate for ML implementation and operations, and Generative AI Developer - Professional for production generative AI development.

Review active AWS AI/ML credentials such as AWS Certified AI Practitioner, AWS Certified Machine Learning Engineer - Associate, and AWS Certified Generative AI Developer - Professional.
Sign in to AWS Certification to confirm whether an existing Machine Learning - Specialty badge is still active and when it expires.
Do not rely on third-party pages that imply MLS-C01 can still be scheduled after March 31, 2026.
Choose an active AI/ML credential based on whether your work centers on AI awareness, ML engineering, or generative AI application development.
Use current AWS exam guides and Skill Builder resources for the active certification you choose rather than retired MLS-C01 prep content.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
