Strong Interest Inventory


  • In 1927 E.K. Strong developed the Strong Vocational Interest Blanks (SVIB)
  • Developed to measure people's interests
  • 420 Items
  • 10 Occupational Scales


- In 1960 20 Basic Interest Scales were added to organize the Occupational Scales and pattern clients' interests

- In 1974 Holland Codes were added to give theoretical structure

- In 1994 the latest Strong Revision was published

- Compares an individual's pattern of responses to the pattern of responses of people of different types and in different occupations


- Sample group

  • Reported satisfied with their careers
  • At least 25 years old
  • Worked in the occupation for 3 years or more
  • Are performing tasks that are "typical" for that occupation
  • Where applicable, hold at least the minimum standards of the occupation


  • The Strong measures interests, not abilities.
  • The Strong does not tell you what you should be.
  • The Strong is most useful when it is used to open up, rather than limit, the world of occupational choice.
  • The Strong should not be used alone as a basis for career or educational choices.
  • Many jobs exist that are not listed on the Strong
  • Large organizations have places for all six Holland codes.
  • No one pattern of responses is better than any other.


  • General Occupation Themes (GOT's)

  • There are 25 scales, 3-5 associated with each GOT.

  • Each scale covers a specific area of content and interest.
  • The scale name provides a good clue to the item content.
