Am y rheswm hwn bydd yr ysgolion lleiaf o ran maint yn cael eu heithrio o'r system fandio. Yn syml, nid yw'n bosibl llunio mesur cadarn a gwrthrychol o safbwynt ystadegau ar gyfer ysgolion mor fach â hyn. I ddechrau, byddwn yn edrych ar ddatblygu dull o weithredu ar gyfer eithrio ysgolion sydd â llai na deg o ddisgyblion sy’n cyfrannu at y mesurau perfformio a gaiff eu defnyddio i fandio. Mae hynny'n gyfystyr â thua 30% o'r ysgolion.
For this reason I shall be excluding the smallest schools from banding. It is simply not possible to produce a statistically robust and objective measure for schools this small. Initially we look at developing an approach of excluding schools who have fewer than ten pupils contributing to the performance measures used in the banding. This represents around 30% of schools.
