From that description they probably want you to cluster by school in the model. The GENLIN command will look something like:

GENLIN PostScore BY Intervention Gender Country WITH PreScore
  /MODEL Intervention Gender Country PreScore
    DISTRIBUTION=NORMAL LINK=IDENTITY
 /REPEATED SUBJECT=School CORRTYPE=UNSTRUCTURED.

Given only 6 countries, I would probably also look at interaction effects for countries, e.g.

/MODEL Intervention Country Intervention*Country Gender PreScore

and then do an EMMEANS command to get the easier to read contrasts table.
