This is a collection of resources curated primarily within the context of the Irish educational system and mostly gathered via the CESI List., if you are based elsewhere you should be aware that your legal duties and contexts may differ from those described in these documents.
Recommended speakers: updated 2017: I asked the CESI list for recomendations in March 2017, and the most recent data below is based on this:
Starting with a very good Overview from Cloina Curley from Cybersafe Ireland:

Just to introduce myself, I'm Cliona Curley, programme director with CyberSafeIreland, which is the Irish children's charity for online safety. Cormac's point about no qualifications being needed is an important one. There are a lot of individuals / businesses now offering their services to schools. Some we have heard great things about, others may be doing more harm than good. Internet safety covers a huge spectrum of different risks and some very sensitive issues - the messaging needs to be right, and it needs to be delivered in an effective and age appropriate way.

There is unfortunately no certification or approval that any provider of these services can get from the Dept of Ed, but my advice for what it's worth would be the following:
  • check out the credentials of the people involved. Knowledge of IT or digital media does not automatically make you an expert in online safety. Do they have access to expertise in online child protection, behavioural change, cyberbullying etc? Do they have good testimonials from other schools on their website?
  • make sure that the trainer feeds back to parents what apps and games that the kids are using and the risks associated with these and tailors the parents talk around this. It's also really important that the emphasis in parents talks is less on simply terrifying them and more on empowering them to do something about it.
  • make sure that any talks are classroom based and not "talking at" large numbers of kids in a hall. Unless kids are actively engaged in the session, it is unlikely to influence how they behave online. It's also really important that this isn't just an annual activity, but that these messages are reinforced often at school (and most importantly at home). The national internet safety website www.webwise.ie has some great resources for this. We've also got some helpful stuff for schools and parents on our website www.cybersafeireland.org, including our new short video for parents which schools are welcome to share with parents on their websites or social media.
Sorry for the rather rambling essay but I hope that helps :)

Regards
Cliona

There was some discussion about the Credentials and expertise of "internet safety speakers", concern being expressed, that there was a functional difference between being an IT expert, and being web aware, and being a useful speaker on the topic.
Respondents also felt it was important to distinguish between a talk for parents, a talk for teachers and a talk for students.

More specific details are given below:
Vivian Purcell: "Highly recommend Speakers from Children of a Digital Age. http://childrenofthedigitalage.com/"

Fionoa MacMenamin Recomended "in my school, secondary, we've had Dr Maureen Griffin in several times. She is excellent, but in demand.
Here is some details https://www.mgmstraining.ie/who-we-are
This year we've also had involvement with http://www.trendmicro.ie/home/internet-safety-for-kids/"
Eoin form Whizzkids responded:
Hi Laurence,
We do this - give internet safety presentations - but it does cost. www.whizzkids.ie I'd be happy to.
These guys also do it: zeeko.com and they are excellent, I think they are based in UCD so I'd say Wicklow would be no problem.
If you are looking for a presentation on a no-fee basis, I know a local primary school got a garda in to talk to the students who was really good, and the fact that he was in uniform added to the drama!
best wishes,
Eoin

IADT do a course on cyberpsychology so they would be worth a prompt
(Mark on the CESI list)

"There was a reasonably good video put together a few years ago by WebWise. ( www.Webwise.ie ) That would probably be worth a look.... it would be an 'outside' voice at any rate."
Conor Galvin (CESI List) Having looked at that site there are some good resources there.

The next two videos are for starting a class discusion. they are short and very good.
