English: When other variables such as the language of assessment, curriculum coverage, socioeconomic status, and teacher quality are controlled, Gatchalian said that the decline in learner outcomes observed may be partially attributable to the implementation of the MTB-MLE, a hypothesis that he said needs further validation.
Filipino: Ayon kay Gatchalian, kung susuriin ang iba pang impormasyon at datos na may kinalaman sa wika ng assessment, curriculum coverage, socioeconomic status, at teacher quality, lumalabas na maaaring nakaapekto sa pagbaba ng marka ng mga mag-aaral ang pagpapatupad ng MTB-MLE. Ngunit para kay Gatchalian, kinakailangan pa ng mas malalim na pagsusuri upang patunayan ito.
