I would agree that poor practice should be challenged wherever it arises:
- Poor practice that allows some schools to 'manage out' or 'take care not to admit' children with SEN.
- Poor practice that means that children - both those with SEN and others - are not kept safe from the direct or indirect consequences of that SEN.
- Poor practice - often accidental, through lack of expertise or training - that means that best practice in the education of children with specific SEN is not applied, or consistently applied.
However, there is also 'unintended less than optimal practice', which may often be beyond the control of those around the child:
- Lack of space in the most suitable setting, leading to a less than optimal placement.
- Limitations of physical design of buildings and the pace at which this can be altered.
- Lack of critical numbers for key potentially beneficial / therapeutic facilities or expertise, whether that be a hydrotherapy pool, a sensory room, an on-site physio etc.
- Lack of knowledge / expertise within that particular local area, in particular for relatively rare conditions.
There are also, even where practice is good, balances to be made between the needs of a specific pupil and the needs of the class. We may not wish that to be the case - the vast majority of education professionals I have worked with want the best for EVERY child in their class and find the compromises that need to be made agonisingly difficult - but the inevitable consequence of group education is that every member of the group has an effect on every other member.
Inclusion that strives to provide all that a highly disabled child needs can actually mean significant isolation of that child as their needs are met primarily in a 1:1 environment. So for example a child with severe learning difficulties, whose educational and care needs are best met through a setting that resembles an early years / nursery class - free flow, multiple activities with different equipment, short adult-led inputs, periods of self-directed activity, appropriate self-care and hygiene routines routines - can absolutely have their needs met within a mainstream 11-18 secondary BUT as a consequence of having their needs met, they will be isolated from their age peers for the vast majority of the school day.
Conversely, there are some children whose inclusion in a mainstream class has such a high impact on the rest of the class that, although the practice around that child is good, the practice for the other SEN children in the class - say 6 or so in a normal class of 30 - is relatively poor, and practice for the remainder of the class is also poor. While we all - parents, educators, educational policy makers, disability specialists - may want to make provision for the most disabled, the most vulnerable members of our classes and society as good as we possibly can, we do also have to have regard for the fact that we have a responsibility to all other children too. This kind of compromise is always the case - if I lined up the parents of every child in every class I have ever taught, and they asked me 'Did you always, in every lesson, at every point in the day, do absolutely everything that you could have done for my individual child?', then the answer would always be 'No'. However the compromise is most stark when a small number of children within the class may have needs so great that the key resources within a classroom - direct adult time, indirect adult time (as in planning, reviewing, discussing, researching, training), space, resources - are primarily devoted to those children.
