Lexia is a very expensive, intensively marketed, US based ICT programme. It is built around the Orton-Gillingham phonics programme developed several decades ago for the remediation of 'dyslexics. It is very clunky and long winded and a modern synthetic phonics programme does the job far better and much faster.
The problem with it being computer based is that it can only 'correct' or support a child with decoding by 'telling' them what the word is that they are struggling with. This, in my experience, is ineffective as it reflects 'whole word learning' rather than learning to decode and blend. 'Telling' a child a word does not guarantee that it will go into long term memory; decoding and blending (once or twice, or several times, depending on the child) will secure words in long term memory but Lexia cannot support this strategy because it cannot monitor and respond to the child's efforts in the way that a person can.
Lexia is also weak at supporting spelling because it cannot teach the essential segmenting skills (listening to the spoken word, breaking it into its phonemes and writing the spelling for each phoneme in the correct sequence); it can only show the child the whole word and expect it to memorise the letter string of which it is comprised.
The only ICT based programme which I know of which is really effective is one called AcceleeReadAcceleeWrite and even that needs a 'person' to monitor the child while using it.
The reason the school is pushing it is probably that they have invested a lot of money in it and been persuaded that it is good by the salesperson! I'd tend to suspect that a school which is using ORT (if it's not the 'new' phonics based ORT) doesn't have a particularly secure grasp of how to teach phonics effectively.
Also surprised that it is being used in YR
