A few assorted facts to help any discussion:
When the question was raised as the system changed, in April 2020 Lincs22 posted on RefChat:
I haven't done any yet, but the training briefings is that - standard is 70. What is expected at this level as been slightly redefined, so expect more 7.0 in the three main categories than previously. If your performance is not better than the expectation, then you will get 7.0.
We also expect more sub 70 scores. The two test scores done indicated a drop in the average mark by between 2.8 and 3.5 per game. And don't think you can make up the marks by doing things tidily.
Alan Wilkie said that a 74/75 now would be a rare as a 78/79 last year - you will need to have a brilliant performance to exceed 75 now.
All observers who cover matches with Level 3 and/or Level 4 referees received initial training, and each had their reports analysed and reviewed to improve consistency.
All observers watching Level 3 and/or Level 4 referees have attended (online) training events each season, with two separate sessions already this time round.
All observers at those levels get access to two LOTG quizzes at the start of the season, plus a monthly online LOTG quiz, with results published (not individual scores)
All observer reports at those levels are likely to be selected at random for quality review at any stage. Every observer gets at least one review per season.
Referees unhappy with an observation report can challenge it, based on the score not reflecting the words, or an error in law. Records are kept of these to arrive at figures showing what percentage are successful, etc.
Most 5/6 Leagues keep a record of observer marks, and share them as an average observer mark and some also publish each observer's average, but typically only at the end of the season.
Where a very low or very high mark is produced, many leagues require the observer to share the report with the Observer Co-ordinator before finalising it.
Each observer can only watch any referee a maximum of twice a season.
The above facts need to be seen in conjunction with the Covid situation, as in 2020 the FA felt that it would take a couple of seasons to get the new system working as they wish (a bit like VAR) but with two seasons curtailed the lead time will extend into this season.
