Online Safety Speakers Scored

Every speaker was researched with the same searches, the same time windows and the same scoring rules. A media item or talk counts as confirmed only when a page outside the speaker's own websites confirms it: the outlet's article, a school or conference page, or an index. Each figure links to where it came from. The counts are floors, not totals: many talks at individual schools are never posted online, and some outlet pages could not be opened, so every speaker has done more than is shown here.

Method

Each criterion converts to 0–5 points, multiplies by its weight, and the total is scaled to 100. The number of talks a speaker gives is not scored, whether confirmed or self-reported, because many school visits are never posted online and speakers differ widely in how much of their schedule they publish. Talks still inform event caliber and recency. Count-based criteria earn one point for each threshold met.

Criterion	Weight	1 pt	2 pts	3 pts	4 pts	5 pts
Media citations, last 3 years	20	1	3	6	12	20
Publications, last 5 years	15	1	3	6	10	20
Months since most recent talk	5	≤36	≤24	≤12	≤6	≤3
Event caliber (judged)	15	local · regional · national · international or TEDx · top-tier headline
Credentials (judged)	10	practitioner · degree or 5+ yrs · senior or 10+ yrs · professor, director or recognised authority · field-defining
Testimonials (judged)	10	one · a few informal · several named organisers · many reputable · extensive top-tier
Audience reach	10	Shown but not scored this round. Confirmed for one speaker only.

Media items are quotes, interviews, features and bylines in established news outlets. They exclude a speaker's own site, blog and podcast, their employer's site, press releases and student newspapers; syndicated copies of one story count once. For event caliber, a talk counts when a host, conference, district or news page confirms it, whether the page was posted before or after the event. For recency, a talk also counts when the speaker's own site or speaker-bureau page lists it with a date that has passed, because many school and private events are never posted publicly; posting dates alone do not count. This rule was applied to every speaker, and only Sameer Hinduja's recency changed under it. Testimonials may come from the speaker's own site, since that is where most are published.

The ranking holds under the main alternatives. Counting only Sameer Hinduja's seven publications that have a publisher page lowers his score to 85.3. Places 2 to 5 are separated by about 5 points, and Katie Greer and Titania Jordan are tied, so a few more confirmed items for any of them could reorder that group.
