Each item presented involves information, analysis or conclusions derived from the scenario.
  • Verbal expression – Assessing your skill in conveying ideas and facts through written language, the NFSI highlights capitalization, vocabulary, punctuation, grammar, spelling and English usage. A short statement with missing words is provided. Select the alternative that correctly completes the sentence and various words in a statement are underlined. Select the alternative containing the word that is spelled incorrectly.
  • Problem Sensitivity – The ability to recognize a problem or the most serious problem is tested through questions requiring you to identify the difficulty in a given scenario. 
  • Deductive Reasoning – Questions assessing this skill require the application of a rule or procedure to a set of circumstances.
  • Inductive Reasoning – A set of events or objects are presented. The task involves a determination of the rule or connection that exists between the individual elements of the set. You will be asked to draw conclusions, find the connecting link or summarize data concerning the series of items.
  • Information Ordering – Rules or procedures are provided. Apply the rules/procedures to statements for the purpose of correctly sequencing the sentences. Items that measure this competency include Questions requiring the selection of the procedure to attend to first/last and sequencing all statements, selecting the alternative containing the correct sentence sequence.
  • Mathematical Reasoning – Expect to encounter charts, tables, diagrams, pictures, and math word problems. Carry out basic mathematical functions to answer the questions using the information contained in the charts.
  • Number Facility – Calculate answers to math word problems using fundamental math functions such as addition, subtraction, multiplication, division, percentages, ratios, decimals, averaging and square measures.
