Largest Domain
Extended Linear Models
MAS-I is currently a three-domain CAS exam with the heaviest emphasis on Extended Linear Models (45-55%), plus Probability Models and Statistics at 20-30% each. CAS uses a 0-10 score scale, with 6-10 meaning pass, and no longer publishes numeric pass marks. The latest official fee schedule lists MAS-I at $550, and starting in 2026 the exam is offered four times per year: January/February, April/May, July/August, and October/November.
About the CAS MAS-I Exam
MAS-I is the first CAS modern statistics exam on the ACAS pathway. The current content outline is built around three domains: Probability Models (Stochastic Processes and Survival Models), Statistics, and Extended Linear Models. It tests both calculation skill and model judgment, especially around GLM selection, diagnostics, and actuarial-style frequency/severity modeling.

Frequently Asked Questions
How many questions are on MAS-I?
CAS's current MAS practice exams use 45 questions and are designed to mirror the real exam experience. The actual MAS-I administration is a 4-hour exam within a 4.5-hour Pearson VUE appointment, and CAS notes that total item counts can vary slightly by sitting.
What score do you need to pass MAS-I?
CAS reports MAS-I results on a 0-10 scale. A passing result is any score from 6 to 10, while failing results are reported from 0 to 5. CAS no longer publishes the underlying numeric pass mark.
What is tested on the current MAS-I outline?
The current outline has three domains: Probability Models (20-30%), Statistics (20-30%), and Extended Linear Models (45-55%). Domain C is the largest section and includes GLM setup, model evaluation, diagnostic plots, offsets, interactions, and statistical-learning-style model interpretation.
What changed for MAS-I in 2026?
The big operational change is frequency: starting in 2026, MAS-I is administered four times per year instead of fewer annual windows. CAS's syllabus/content-outline updates page also shows no MAS-I source-material changes from the January/February 2026 administration to the April/May 2026 administration.
What item types can appear on MAS-I?
The current CAS MAS-I content outline lists multiple choice, multiple selection, point and click, fill in the blank, and matching as possible CBT item types. Even when you practice with standard multiple-choice questions, you should still be comfortable interpreting tables, plots, and model output quickly.
What prior knowledge does CAS assume before MAS-I?
In the Syllabus of Basic Education, CAS states that MAS-I assumes prior knowledge from Exam 1 and Exam 2. That means probability distributions, expectation, interest theory, and core actuarial mathematics should already be comfortable before you try to move fast through MAS-I-style modeling questions.
How should I study for MAS-I efficiently?
Build your plan around the weightings: lock down Probability Models and Statistics so you can bank routine points, then spend most of your time on Extended Linear Models. Work timed problem sets with tables and plots, and practice explaining why one model, link, or diagnostic conclusion is better than another instead of memorizing formulas in isolation.
