There's no fixed standard; it's a matter of showing over a number of years that the team would have the ability to be competitive at the very top level of cricket.
Test matches are the highest level of cricket although, statistically, their data forms part of first-class cricket. Matches are played between national representative teams with "Test status", as determined by the International Cricket Council. As of December 2014, ten national teams have Test status, the most recently promoted being Bangladesh in 2000. Zimbabwe's Test status was voluntarily suspended, because of poor performances between 2006 and 2011; it returned to competition in August 2011.[9 countries]
In January 2014, during the historic ICC meeting in Dubai, the pathway for new potential test nations was laid out with the winners of the next round of the ICC Intercontinental Cup playing a 5-day match against the bottom rank test nation. If the Associate team defeats the test nation, then they could be added as the new test country and be given full membership.
