SPELT-3 / SPELT-3 Spanish

Hi there! Does anyone use the SPELT-3 assessment in the schools? What are your thoughts on it and would you recommend purchasing the assessment?

I’m particularly interested in adding the SPELT-3 Spanish to my toolkit for Spanish speaking ELLs. I tend to hear a lot about the BESA, PLS-5 Spanish, and the CELF-4 Spanish, but I never see discourse about the SPELT.
