Details of the changes in terminology are revealed in an internal DfE memo, split into two columns for words used before 11 May (when the coalition took office) and those with which they should be replaced.
Key changes to phrases in the children's sector include the replacement of safeguarding with child protection, children's trusts with "local areas, better, fairer, services'" and using the term "help children achieve more" in place of Every Child Matters or the five outcomes.
John Chowcat, general secretary of children's services union Aspect, said he fears the change in language represents a gradual move away from the Every Child Matters agenda by the government. "I could not imagine this government making a bold announcement to the effect that Every Child Matters has gone or anything like that," he said.
"The impact that would have in terms of demoralising the children's workforce would be significant, but I can see a step-by-step shifting of the approach to the agenda. Although this change may be to do with language alone, what is happening suggests we need to be careful about the future of Every Child Matters."
Wes Cuell, NSPCC director of services for children and families, said: "We hope the coalition will continue to work for better outcomes for children. We are not bothered about the terminology as long as it stays committed to better outcomes. Any signs it is not would be a big issue."
Anne Longfield, 4Children chief executive, said she is confident the principles will continue to be followed on the ground. "The principles of Every Child Matters are observed in the field and people will continue to use those approaches even if they might not refer to it in the same way."
The government has denied that changes to terminology outlined in the document indicate a change of policy direction. "There is no lack of focus on Every Child Matters," a DfE spokesman said. "The coalition created the new DfE to carry through radical reforms in schools, early years and child protection.
