„Low basic skills among adults remains an acute challenge facing the English education system. One third of the potential entrant pool to university (age 16-19) has low basic skills, higher than almost all other countries surveyed by PIAAC. Early intervention is needed to improve basic skills during compulsory education, since later remediation is more challenging.“
