The ALL study measured three following domains that included a common set of skills:
"This definition draws attention to the fact that panel members view literacy not as a set of isolated skills associated with reading and writing, but more importantly as the application of those skills for specific purposes in specific contexts. It is meant to capture the full scope of situations in which literacy plays a role in the lives of adults, from private to public, from school to work, to lifelong learning and active citizenship."

"This brief definition of numeracy is much broader than the definition of Quantitative Literacy as used in the IALS. Its key concepts relate in a broad way to situation management and to a range of effective responses (not only to application of arithmetical skills). It refers to a wide range of skills and knowledge (not only to computational operations) and to a wide range of situations that present actors with mathematical information of different types (not only those involving numbers embedded in printed materials)".

"The problem solver has a more or less well-defined goal, but does not immediately know how to reach it. The incongruence of goals and admissible operators constitutes a problem. The understanding of the problem situation and its step-by-step transformation, based on planning and reasoning, constitute the process of problem solving."

The ALL Problem Solving domain was not administered in the United States, but was part of the ALL study in Australia, Bermuda, Canada, Hungary, Italy, New Zealand, the Netherlands, Norway, and Switzerland.
