Spearman rho is appropriate for use when the data is ordinal, which is the case for the rankings of educational outcomes by both teachers and pupils. Pearson's r is appropriate for use when the data is continuous and normally distributed, which is not the case here. The Phi coefficient is appropriate for use with nominal data, which is also not the case here. Therefore, the best choice for this data is Spearman rho.
