Written Comprehension -- The ability to read and understand information and ideas presented in writing. Inductive Reasoning -- The ability to combine pieces of information to form general rules or conclusions (includes finding a relationship among seemingly unrelated events). Deductive Reasoning -- The ability to apply general rules to specific problems to produce answers that make sense. Near Vision -- The ability to see details at close range (within a few feet of the observer). Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Memorization -- The ability to remember information such as words, numbers, pictures, and procedures. Flexibility of Closure -- The ability to identify or detect a known pattern (a figure, object, word, or sound) that is hidden in other distracting material. Category Flexibility -- The ability to generate or use different sets of rules for combining or grouping things in different ways. Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving thWritten Comprehension -- The ability to read and understand information and ideas presented in writing.

Analyzing Data or Information -- Identifying the underlying principles, reasons, or facts of information by breaking down information or data into separate parts. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Documenting/Recording Information -- Entering, transcribing, recording, storing, or maintaining information in written or electronic/magnetic form. Making Decisions and Solving Problems -- Analyzing information and evaluating results to choose the best solution and solve problems.
