AWS MLS-C01 Practice Test & Replacement Route

Review AWS MLS-C01 replacement-route guidance, Machine Learning Specialty practice options, and the current AWS MLA-C01 and AIP-C01 routes in IT Mastery.

MLS-C01 was AWS Certified Machine Learning - Specialty. AWS’s exam guide listing shows March 31, 2026 as the last day to test for this exam code, so this page stays live for candidates who still search the older specialty route.

The closest current IT Mastery route for machine-learning engineering is AWS MLA-C01 Practice Test: ML Engineer Associate . If your MLS-C01 search is mostly about production generative AI applications, compare AWS AIP-C01 Practice Test: GenAI Developer Pro as well.

Current route to use: MLA-C01 Machine Learning Engineer Associate. This page is for older-code search intent and replacement-route guidance.

Avoid stale MLS-C01 preparation

  • Do not build a new study plan around MLS-C01 without checking the current AWS route first.
  • Reuse older notes only after mapping them to current MLA-C01 or AIP-C01 objectives.
  • Treat specialty-era SageMaker, data-preparation, model-evaluation, and deployment concepts as background, not as proof that your material still matches the current exam.
  • If an employer, course, or forum still says MLS-C01, translate the intent into the current AWS certification family before buying materials.
