LOL! No labcoats, but plenty of aprons for the cookery and woodwork classes.
I saw that first series as well (kids put through a few weeks of 1950s-style education). The thing that sticks in my mind from that first run is the exam results.
The 16-year-olds were all slated to get passes in their GCSE's, the modern exams taken by school-leavers. One of the first things they did at their "1950s" school was to sit what they assumed to be O-level papers, the equivalent exams before the GCSE was introduced. Over half of them flunked miserably (results down in the 20% range in some cases).
It was then revealed that the exams they had taken were not in fact old O-levels intended for 16-year olds, but a 1950s "11-plus" paper, an exam given to 11-year-olds to assess their skills for entering high school.
Anyway, back to the second series, and the mistake wasn't the wrong type of plug, but the wrong type of flex. We were told that this was supposed to be the mid-1960s, yet the cord they had been given to wire up correctly had brown, blue, & green/yellow color coding. At the time in question, Britain was still using our traditional red/black/green. Oops!
P.S. BS546 (round-pin) plugs were still in widespread use in the 1960s, although BS1363 was being used for most new installations, other than "special" applications such as theatres.
