A school which brought in a "no physical contact" rule for its pupils has reviewed and scrapped the policy.
Parents had claimed some children at Philip Morant School and College in Colchester were given detentions for hugging or high-fiving their friends.
The school backtracked following criticism, and on Monday, it published a five-page slideshow document outlining what level of physical contact was appropriate, which included handshakes and "fist bumps".
Head teacher Stephanie Neill said staff had worked "closely" with students on the policy.
Students were told about the no physical contact policy in assemblies at the start of term.
Neill explained the approach was introduced after "an increase in overly physical behaviour last term that disrupted learning and raised safety concerns".
An online petition was subsequently set up protesting against the rule, which attracted more than 350 signatures.
Handshakes and 'dapping'
About three weeks ago, the school backtracked, and Neill said an "appropriate" level of physical contact was once again permitted.
The school said it then consulted with families and "student leaders", before publishing its comprehensive document via its website this week.
Examples of "appropriate" physical contact included:
Dapping (which is a more informal variation of a handshake)
Fist bumps
High fives
The school said these greetings were only permitted under certain conditions, including if:
Both people had consented
It was not malicious or disrespectful
Did not cause people to be late
Did not involve "bone squashing"
Did not take place in classrooms
Other examples given as acceptable physical contact included holding hands, a "tap on the shoulder" to get attention or a hug.
Tripping up and "birthday bumps" were not acceptable.
"We would also praise our students who have continued to conduct themselves as we would expect," Neill said in her latest statement.
When asked about the no physical contact policy last month, the Department for Education said it provided guidance and measures to help schools make their own choices.
