This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Very few interviewees reported learners receiving the intended two 15-minute sessions each week, with pupil and staff absences and scheduling cited as causes. → National Foundation for Educational Research (NFER) 2014
q2 i? The most commonly reported barrier was lack of TA time to plan, prepare and fit sessions into the existing timetable. → National Foundation for Educational Research (NFER) 2014 (2)

Qualitative process evaluation based on telephone interviews with 25 TAs and 24 coordinators across 27 schools (N=49 participants), plus training observations and TA questionnaires. Fidelity to the intended 60-session dosage was rare.
"Very few interviewees reported that learners had received two 15-minutes sessions each week. TAs tried to adhere to the intervention where possible, but pupils or staff absences prevented this from happening."

In the same interview study, the most cited barrier to delivery was "A lack of time, specifically around TAs having sufficient time to plan and prepare for the sessions", mentioned by ten TAs and 12 coordinators; pupil absence, pupil attitudes, resources, location and senior-management support were also named.
"A lack of time, specifically around TAs having sufficient time to plan and prepare for the sessions and also finding time to fit in two 15-minute sessions each week within the existing school timetable. This was mentioned by ten TAs and 12 coordinators."
