MMPI Test Online Free Preparation & Tips – 2024

MMPI Personality Test

Job seekers have gotten accustomed to sitting for pre-employment aptitude tests when applying for their desired jobs. These tests serve as a means to not only test their academic fortitude but to evaluate their psychological makeup, especially for stressful and high-risk positions. High school and college graduates are not exempt from these assessments, as their academic qualifications do not provide any relevant information about their psychological profile.

What Is the MMPI Test?

The Minnesota Multiphasic Personality Inventory, also known as the Minnesota Personality Test,  is a pre-employment screening test used worldwide. It was developed at the University of Minnesota in the 1930s by Starke R. Hathaway and J. C. McKinley. The exam initially published in 1943, was later updated in 1989 to the now popular MMPI-2 exam.  There are two other versions of the test; One for adolescents, the MMPI-A and a restructured version, the MMPI-2-RF. The exam must be taken in an assessment center with a psychologist present trained to administer the exam.

MMPI-2 is offered in 22 languages.


What Is the Format of the MMPI Test?

There are three variants as expressed above, but the MMPI-2 and the MMPI-2-RF are the two more popular variants.

Both the MMPI-2 and MMPI-2-RF are untimed exams. The MMPI-2 consists of 567 questions which candidates generally complete in approximately 90 minutes. The test has nine validity scales to aid in the prevention of fake answers.

First published in 2008, the MMPI-2-RF is based on the 2003 Restructured Clinical Scales. The exam consists of 338 questions taken from the MMPI-2 and is taken in situations where the MMPI-2 cannot be administered. Due to there being fewer questions, it usually takes a shorter time of about 35-50 minutes to complete.

The MMPI-2 remains the more popular of the two, being the third most popular psychometric exam behind the IQ test and Achievement tests.



The Minnesota Multiphasic Personality Inventory, commonly known as the MMPI, is a foundational tool in psychological assessment, particularly in the context of employment. Developed to assess adult personality and psychopathology, this test is instrumental in distinguishing various psychiatric diagnoses. It also plays a crucial role in guiding the selection of appropriate treatment programs and directing candidates to suitable positions. The MMPI is characterized by its comprehensive nature, consisting of over 500 statements that require a true or false response. The flexibility of its administration, whether manual or online, individually or in groups, coupled with an average completion time of 1 to 1.5 hours, makes it a versatile tool in a wide range of settings. While it is a significant factor in employment decisions, it is typically used in conjunction with other assessments for a well-rounded evaluation.


The MMPI-2

Building upon the foundation of the original MMPI, the MMPI-2 serves as an updated and enhanced version, reflecting the evolving landscape of psychological assessment. This version was developed to include a more diverse population sample, thereby increasing its relevance and applicability in modern settings. The MMPI-2 consists of 567 carefully crafted statements, and its completion spans between 1 to 2 hours. This version has gained prominence in the psychological community, recognized as the third most common psychological test, trailing only behind IQ and achievement tests. Its application extends beyond the clinical domain, encompassing forensic and employment contexts, offering a nuanced understanding of an individual’s psychological makeup.



The MMPI-2-RF represents a streamlined version of the MMPI-2, designed to provide a quicker yet equally reliable assessment. This version is particularly beneficial in situations where the comprehensive MMPI-2 is not practical or necessary. Comprising 338 statements, the MMPI-2-RF offers a more concise evaluation, reducing the test duration to approximately 35-50 minutes. Its utility is especially noted in specific research contexts, such as child custody law studies, where a shorter assessment period is required without compromising the depth and integrity of the evaluation.


MMPI’s Clinical, Content, and Validity Scales

The MMPI test, in its various iterations, employs a multifaceted approach to psychological assessment through its Clinical Scales, Content Scales, and Scoring and Validity Scales. The Clinical Scales are designed to measure specific psychological conditions such as Hypochondria, Depression, Hysteria, and others, providing insights into an individual’s mental health and personality traits. Complementing these are the Content Scales, which delve deeper into specific aspects of personality and behavior, including Anxiety, Fears, Obsessiveness, and more, offering a nuanced view of the test-taker’s psychological profile. The Scoring and Validity Scales play a crucial role in ensuring the accuracy and integrity of the test results. They involve sophisticated scoring mechanisms where responses are converted to normalized “T scores,” allowing for individualized analysis. These scales also include measures like the L Scale, K Scale, and others, which assess the test-taker’s response honesty and consistency, ensuring the reliability of the test outcomes. Together, these scales form a comprehensive framework that makes the MMPI a robust tool in psychological evaluation, adept at uncovering a wide range of psychological states and tendencies.


The MMPI Scoring & Reporting

The MMPI-2 has a number of reporting options that are currently being used. They are as follows:

  • Extended Score Report
  • The Minnesota Report: Adult Clinical System, 4th Edition Interpretive Report
  • The Minnesota Report: Revised Personnel System, 3rd Edition Interpretive Report
  • The Minnesota Report: Revised Personnel System, 3rd Edition Adjustment Rating Report
  • The Minnesota Report: Reports for Forensic Settings

The report filed is dependent on the purpose of the exam and the job in question. For example, the Minnesota Report: Adult Clinical System, 4th Edition Interpretive Report is provided in the evaluation and management of substance abuse patients while The Minnesota Report: Revised Personnel System, 3rd Edition Interpretive Report, is presented when evaluating persons for occupations such as law enforcement officers, emergency response teams, and pilots.


How to Pass the MMPI Test?

Study guides will not provide you with the holy grail to passing this exam, but they might be able to give you some rewarding tips. One of which is to expose yourself as much as possible to the exam material. This can be done by attempting MMPI questions and practice assessments. This process helps you to optimize your responses to suit the psychological profile best aligned to your desired job.

Being familiar with this material from repeated practice and study sessions provides the candidate with added confidence which allows them to answer the questions with little hesitation and increased clarity. The MMPI test is not timed, and therefore there is no rush to complete the questions. It still may help however to attempt the practice questions in an environment more in line with the conditions expected at the assessment center.



The job market has become increasingly competitive, and passing assessments such as the MMPI-2 may be an integral part of a company’s onboarding process. Knowing this, I think it’s safe to say it would be in your best interest to double down on your preparation efforts and make the opportunity count.

All the best with your journey to landing that dream job!
