A resolution to this effect was adopted at the ongoing 21st Congress for holding the plenary meeting, which is being held after the last one in 1978 at Salkia in West Bengal.
The party's membership has remained virtually stagnant at 11 lakh, while that of some of its mass organisations like the students wing SFI has shown a decline.
"Despite this, many shortcomings and weaknesses are continuing and the party has not been able to register substantial progress and increase its independent strength," it said, adding that the meet would be held before the end of this year.
In the run up to the plenum, the Politburo will prepare a questionnaire on the basis of which state committees will frame reports on the organization's status, specific problems and suggest the ways to tackle them.
"The Politburo will study these state reports and prepare a draft report and present it before the central committee for its consideration. After necessary amendments by the central committee, the draft report will be sent to the state committees.
"The state committees will then send their views on the draft report to Politburo and central committee on the basis of which a revised report will be presented to the Plenum," a CPI(M) statement said.
