Be careful
This document suggests that they are using ESAP funding in the place of statements while awaiting Stat Assessment. The same as you have been told.
And, it is said on page 3:
"The use of ESAP Funding may well be an appropriate interim measure in an emergency situation. This will provide funding in the short term whilst further information can be collected."
But (page 1):
"Lancashire has introduced Enhanced School Action Plus (ESAP) funding. This is for pupils who meet the criteria for Statutory Assessment but whose needs can be met in mainstream schools without very high levels of additional funding (Band A, B or C).
It is expected that Statutory Assessment will only be required for pupils who have particularly severe or complex enduring special educational needs."
BE Worried read here:
"Enhanced School Action Plus Funding
When the Authority received an RSA and/or when it completes a Statutory Assessment, the decision may be made that the pupil's needs can be met through ESAP Funding. In these cases, an ESAP Funding Agreement will be drawn up and either the Statutory Assessment refusal letter or a Note in Lieu will be issued, (whichever is relevant)."
It sounds like you need to make very sure that your DS is not just being fobbed off with a small bit of funding when he needs a legal document.
