The format might vary for own-admission authority schools, but one would have thought it would tend to be the same for LA schools in the same area.
The actual requirements are set out in the Code:
The admission authority must supply ........ :
a) a written statement summarising how places at the school were allocated (without disclosing personal details of applicants which would enable identification of individuals) and how the admission arrangements for the school apply to the appellants’ application, accompanied by any relevant background information and documents on which they placed substantial reliance (such as the appellants’ application form or references from religious ministers). Where distance criteria have been used to allocate places, admission authorities must demonstrate how this was applied to the appellants’ application compared to those offered a place;
b) a written statement summarising the reasons for the decision (and attaching a copy of the decision letter), explaining how admission of an additional child would cause prejudice to the provision of efficient education or use of resources, making it clear whether or not the admission authority is defending its decision on the basis of infant class size legislation. The admission authority must include a summary of the school’s net capacity and could also include a map/plan of the school if this would be helpful. Admission authorities’ statements referring to accommodation, class sizes, capacity etc, must be supported by factual information, as panel members cannot undergo ‘tours’ of schools to make their own assessments, as it could call into question their independence and lead to allegations of lobbying;
c) the relevant extract of the area’s coordinated admissions scheme where this is relevant to the appeal (e.g. a parent or child appealing for a place at a school they ranked lower on their common application form than the one offered under the scheme) and, in the case of a voluntary aided or foundation school or an Academy, a statement from the local authority explaining how the scheme was applied;
d) details of how the locally agreed Fair Access Protocol operates, where relevant .......; and
e) copies of any information or documents that will be supplied to the panel at the hearing, including any documents that have been submitted by appellants.
The appeal panel must ensure that the papers that have been issued to the parties are complete and comprehensive; it is for the panel only to consider what material may be relevant and what weight to give it.
[The panel must consider the following issues .....] Whether or not there would be prejudice caused by the additional admission of the child. Where this is the case, the admission authority must be able to demonstrate this over and above the fact that the published admission number has already been reached. The panel must consider a number of factors in reaching a decision as to whether or not there would be prejudice. This may include considering, in light of current school organisation and structure, what effect an additional admission would have on later year groups (i.e. 'future prejudice') or, if the application was for a year group other than the normal year of entry, whether any changes have been made to the school’s physical accommodation or organisation since an admission number was originally set for that year group. The panel can decide what weight to give the arguments presented.
The admission authority concerned may submit, as part of its evidence to the panel, that the child in question has been allocated a place at an alternative school. This may be of particular relevance where the question of distance between home and school is being discussed. Equally, it is open to the appellant to state any reasons why an alternative school would be less suitable. With coordinated admissions schemes, this may be appropriate where an appellant is appealing against refusal of admission to one preferred school, but has either been offered a place at another preferred school or, if none of their preferences could be met, has been allocated a place at an alternative school. However, how an appellant has ranked their preferences on the common application form (e.g. if they are appealing for a lower ranked preference school than the one they have been offered) need not be a factor in the panel’s consideration unless this is directly relevant to the grounds for appeal.
