The charity, which rebranded from The Dyslexia Institute earlier this year, wants to ensure all MPs and members of the House of Lords are aware of the resources available to dyslexics and those working on their behalf when local cases arise.
InHouse, which is run by two former Conservative Central Office staff, will also highlight Dyslexia Action's belief that unrecognised dyslexia costs the UK economy £1bn a year.
The charity lobbies on behalf of dyslexics and offers them services and support.
In line with the findings of this year's Education and Skills Select Committee on children with Special Educational Needs (SEN), it is also calling for more ‘ring fenced' funding to ensure better support for SEN children.
The charity also wants improved teacher training to better identify those children at risk and provide more appropriate support.
InHouse PR director Jo Tanner heads the account, reporting to Dyslexia Action head of marketing and communications Ann Campbell. ‘We've appointed InHouse to bolster our public affairs work and support our existing contact with Westminster,' said Campbell.
Tanner said her agency - which she launched with Katie Perrior in April (PRWeek, 14 April) - will work on the project for six months, during which time it will also highlight the number of dyslexic prisoners.
