The charity is in the process of finalising a shortlist, with the deadline for RFI responses understood to have passed at the end of last week.
NSPCC director of communications Ali Jeremy said: "The NSPCC is looking to establish a small roster of PR agencies to provide support across fundraising, public education and influencing campaigns that will help raise awareness of our vital services, including the NSPCC helpline and ChildLine. Work will be awarded on a project-by-project basis."
The issue of child abuse remains high on the news agenda after revelations around the late Jimmy Savile sparked a string of arrests under Operation Yewtree, with Max Clifford sentenced to eight years in jail two weeks ago for a string of indecent assaults against teenage girls.
Last year the charity launched The Underwear Rule, encouraging parents to speak to children about the issue of sexual abuse, and following Clifford’s verdict it tweeted:
#MaxClifford thought no one would believe his victims. He was wrong. This sentence proves victims of non-recent abuse can get justice.— NSPCC (@NSPCC) May 2, 2014
Last month PRWeek sister title Campaign revealed that the charity was reviewing its creative advertising account with FCB Inferno.
