(a) in paragraph (1) after “2010-2011” insert “or 2020-2021”; and  (b) for paragraph (3) substitute—  (a) in relation to the 2010-2011 school year, to the training of teachers who teach  pupils in the first or second key stages (as defined in section 82 of the Education  Act 2002( a ));  (b) in relation to the 2020-2021 school year, to the training of teachers in connection  with arrangements for pupils to undergo, on the school premises, lateral flow tests  capable of detecting the presence of severe acute respiratory syndrome coronavirus  2 (SARS-CoV-2).”.  “(3) Paragraph (1) applies—  Nick Gibb Minister of State  Department for Education  29th April 2021  EXPLANATORY NOTE  (This note is not part of the Regulations)  These Regulations amend the Education (School Day and School Year) (England) Regulations  1999 (“the 1999 Regulations”), which set out the minimum number of school sessions that must  be held during a school year in every school maintained by a local authority and every special  school not maintained by a local authority.  Regulation 3(2) of these Regulations amends regulation 3(6) of the 1999 Regulations and inserts a  new paragraph (7). The effect is to reduce the minimum number of sessions which must be held in  the school year 2021-2022 from 380 to 378. This is to enable relevant schools to close for the  additional bank holiday announced on 12th November 2020 to take place on 3rd June 2022 to  celebrate the Platinum Jubilee of Her Majesty the Queen. This amendment also preserves similar  reductions that were made in previous regulations for the school years 2010-2011 and 2011-2012.  Regulation 3(3) of these Regulations amends regulation 4 of the 1999 Regulations. The effect is  that up to two sessions in the school year 2020-2021 can be counted towards the minimum number  of sessions held during that year even if they are devoted wholly or mainly to the training of  teachers rather than the teaching of pupils. This is so that where a relevant school held an  additional “inset” day on 4th January 2021 to help teachers train and prepare for coronavirus  testing in schools this is counted as a session for which the school met.
