In 1835 Symons received a commission from the Home Office to inquire into the state of the hand-loom weavers and manufacturers. He travelled for it in Lancashire and Scotland, and parts of Switzerland. He then held a tithe commissionership, and was a commissioner to inquire into the state of the mining population of the north of England.[1]
In 1843 Symons was called to the bar at the Middle Temple. He went the Oxford circuit, and attended the Gloucester quarter sessions. During this period of his life he was editor of the Law Magazine, up to its union with the Law Review in 1856. In 1846 the Committee of Council on Education appointed him as one of the commissioners to collect information on the state of education in Wales. The reports of the commissioners were published in 1848.[3] The publication of the reports in Wales caused uproar because of the perception that they disparaged the Welsh, which incited the criticism of treachery, see Treachery of the Blue Books.
In 1848 Lord Lansdowne made Symons one of Her Majesty's permanent inspectors of schools, a post he retained through life.[1] He also concerned himself with the establishment of reformatories for juvenile criminals, drawing attention to the "colony" at Mettray in France.[4]
Symons died at Malvern House, Great Malvern, on 7 April 1860.[1]
