It was ranked red by the Welsh government categorisation scheme in 2015, but made considerable improvements in 2016.

[2] The Sixth Form was a member of the "Haverfordwest federation", which linked it with Sir Thomas Picton School and Pembrokeshire College.

[3] Thomas Lloyd, of Cilciffeth near Llanychaer, endowed the school with property in his will dated 22 November 1612.

Due to budget concerns from Pembrokeshire County Council in addition to the underperforming GCSE and A Level results from both schools over a period of a few years, the decision was made to merge Tasker Milward V.C.

[9] The school had three buildings located on site: The Milward Building (Bottom School), housed the English, Maths, Chemistry, Physics, Physical Education departments and the library; the Humanities Block (H Block), where the Geography, Geology, History and RE departments were based ("H Block" was built in 2001); and the Tasker Building (Top School), where the Welsh, MFL, Biology, ICT, Drama, Media Studies, Music, Technology and Art departments were based.

This Tasker Building also catered for the Sixth Form, providing a computer/work area and a common room.

On 20 August 2013 the school was accused of having a sex education policy that referenced Section 28 (a now repealed act).

The then headteacher, Maggie Haynes, apologised for any distress that the failure to remove the old policy from the website may have caused.
