Does anyone know how ORT levels 12 - 16 compare to Collins Big Cat levels 12 - 16(+)?
I can find a NC level chart for CBC but not ORT (I know these are rough guides). The CBC NC levels seem lower than ORT, or the national tables I've seen for levels 1 - 11 (e.g. CBC lime isn't equivalent to L3c).
Many thanks to anyone that can help me get my head round these higher levels.
