====1965 regulations====
Concerns were raised that the 1957 regulations were too lax. At the FIDE Congress in 1961, GM [[Milan Vidmar]] said that the regulations "made it possible to award international titles to players without sufficient merit". At the 1964 Congress in [[Tel Aviv]], a subcommittee was formed to propose changes to the regulations. The subcommittee recommended that the automatic award of titles be abolished, criticized the methods used for awarding titles based on qualifying performances, and called for a change in the makeup of the Qualification Committee. Several delegates supported the subcommittee recommendations, including GM [[Miguel Najdorf]] who felt that existing regulations were leading to an inflation of international titles.<ref name="Harkness1967"/> At the 1965 Congress in [[Wiesbaden]] FIDE raised the standards required for international titles. The International Grandmaster title regulations were:
* 1. Any World Champion is automatically awarded the GM title
* 2a. Anyone who scores at least 40 percent in a quarter-final match in the Candidates Tournament
* 2b. Scores at least the number of points in a tournament corresponding to the total of a 55 percent score against Grandmasters plus 75 percent against [[International Masters]] (IM) plus 85 percent against other players (a GM "[[Norm (chess)|norm]]").

To fulfill requirement 2b, the candidate must score one GM norm in a category 1a tournament or two norms within a three-year period in two Category 1b tournaments, or one Category 2a tournament and one Category 1b tournament.

The categories of tournaments are:
* 1a—at least sixteen players, at least 50 percent are GMs and 70 percent at least IMs
* 1b—at least twelve players, at least 33⅓ percent GMs and 70 percent IMs
* 2a—at least fifteen players, at least 50 percent IMs
* 2b—ten to fourteen players, at least 50 percent IMs.
Since FIDE titles are for life, a GM or IM does not count for the purposes of this requirement if he had not had a GM or IM result in the five years prior to the tournament.

In addition, no more than 50 percent plus one of the players can be from the same country for tournaments of 10 to 12 players, or no more than 50 percent plus two for larger tournaments.

Seventy-four GM titles were awarded in 1951 through 1968. During that period, ten GM titles were awarded in 1965, but only one in 1966 and in 1968.<ref>{{Harvard citation no brackets|Sunnucks|1970|pp=224–226}}</ref>
