^5.2.2
In order to award 25% extra time the SENCo must determine the needs of the candidate based on one of the following documents:
• a current Statement of Special Educational Needs, or an Education, Health and Care Plan, or an Individual Development Plan, which confirms the candidate’s disability (see pages 23 and 26 for the required centre based evidence); or
• an assessment (Part 2 of Form 8) carried out no earlier than the start of Year 9 by an assessor confirming a learning difficulty relating to secondary/further education.^
Does your daughter have a statement of special education needs or an EHCP or an Individual Development Plan?
If you read section 7, the assessment referred to (form 8) should be completed by an assessor employed by the exam centre, so why are the school pushing you to get this completed privately?
^7.3.5 The assessor should ideally be employed within the centre. Alternatively, the assessor is:
• employed at another centre, e.g. within an Academy chain; or
• employed by the Local Authority; or
• an external assessor who has an established working relationship with the centre or, before an assessment, establishes a relationship with the centre.^
You do not require the same for a Reader though as per your OP, just a letter from the SENCO - 5.5.5

5.5.5
The SENCo must produce a short concise file note on centre headed paper, signed and dated, confirming the nature of the candidate’s impairment and that the use of a computer reader
and/or a reader reflects his/her normal and current way of working within the centre.
For candidates with learning difficulties assessment evidence and Form 8 is no longer required.
However, the SENCo must be satisfied that:
• the candidate has an impairment which has a substantial and long term adverse effect, giving rise to persistent and significant reading difficulties; and
(The candidate is disabled within the meaning of the Equality Act.) • there is a genuine need for the arrangement.
A computer reader/reader will be awarded on account of:
• cognition and learning needs;
• communication and interaction needs;
• a medical condition;
• sensory and physical needs;
• social, mental and emotional needs.^
