The Item-Difficulty Index in the educational field is useful in testing for validity of test question. it is known as the amount or percentage of students who answer the test questions correctly. it is often called P-value. Item-Difficulty has the range of 0-100. the formula is achieve by the number of students who answer a question correctly divided by the total number of students in the class who answered the question(s).
