The consultation document makes no mention of an earlier Education Commission ideal, that through-train schools, in which students can move seamlessly from primary to secondary levels, should be encouraged so that they could avoid the stresses of going through an allocation process - the ultimate solution to the banding and allocation problem. Michael Tien Puk-sun, chairman of the working group, insisted the omission of through-train schools did not reflect any policy change. 'Yes, we are still encouraging them,' he said, adding that he understood concerns that it would be more difficult for English-medium secondary sections adopting the through-train model to achieve the 85 per cent threshold of students able to learn in English, because of their mixed ability intake. 'It is a concern that is valid. We will look at how to work out a solution,' he said. George Tam Siu-ping, chairman of the Grants Schools Council, told legislators at an education panel meeting this week that there should be an alternative policy for these schools.
